Allow pressing 'q' to abort the running tasks, then 'R' to retry (#1289)

If you press 'q' while `PlugInstall` or `PlugUpdate` is in progress,
the current version of vim-plug immediately closes its window and aborts
all the running processes.

This commit enhances the 'q' map so that it doesn't close the window,
but instead displays the aborted tasks so that the user can press 'R' to
retry the tasks.

Fix #1285

+1. End the section with `call plug#end()`
+
+For example,
 
 ```vim
-call plug#begin('~/.vim/plugged')
+call plug#begin()
 
-" Make sure you use single quotes
+" List your plugins here
-Plug 'junegunn/seoul256.vim'
+Plug 'tpope/vim-sensible'
-Plug 'junegunn/vim-easy-align'
-
-" On-demand loading
-Plug 'scrooloose/nerdtree', { 'on':  'NERDTreeToggle' }
-Plug 'tpope/vim-fireplace', { 'for': 'clojure' }
-

-Plug 'nsf/gocode', { 'tag': 'go.weekly.2012-03-13', 'rtp': 'vim' }
-
-" Locally-managed plugin
-Plug '~/.fzf'
 
 call plug#end()
 ```
 
-Reload .vimrc and `:PlugInstall` to install plugins.
+Reload the file or restart Vim, then you can,
 
-### Commands
+* `:PlugInstall` to install the plugins
+* `:PlugUpdate` to install or update the plugins
+* `:PlugDiff` to review the changes from the last update

-### Keybindings
+## Examples
+
+The following examples demonstrate the additional features of vim-plug.
+
+### Vim script example
+
+```vim
+call plug#begin()
+" The default plugin directory will be as follows:
+"   - Vim (Linux/macOS): '~/.vim/plugged'
+"   - Vim (Windows): '~/vimfiles/plugged'
+"   - Neovim (Linux/macOS/Windows): stdpath('data') . '/plugged'
+" You can specify a custom plugin directory by passing it as the argument
+"   - e.g. `call plug#begin('~/.vim/plugged')`
+"   - Avoid using standard Vim directory names like 'plugin'
+
+" Make sure you use single quotes
+
+" Shorthand notation for GitHub; translates to https://github.com/junegunn/seoul256.vim.git
+Plug 'junegunn/seoul256.vim'
+
+" Any valid git URL is allowed
+Plug 'https://github.com/junegunn/vim-easy-align.git'
+
+" Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
+Plug 'fatih/vim-go', { 'tag': '*' }
+
+" Using a non-default branch
+Plug 'neoclide/coc.nvim', { 'branch': 'release' }
+
+" Use 'dir' option to install plugin in a non-default directory
+Plug 'junegunn/fzf', { 'dir': '~/.fzf' }
+
+" Post-update hook: run a shell command after installing or updating the plugin
+Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
+
+" Post-update hook can be a lambda expression
+Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
+
+" If the vim plugin is in a subdirectory, use 'rtp' option to specify its path
+Plug 'nsf/gocode', { 'rtp': 'vim' }
+
+" On-demand loading: loaded when the specified command is executed
+Plug 'preservim/nerdtree', { 'on': 'NERDTreeToggle' }
+
+" On-demand loading: loaded when a file with a specific file type is opened
+Plug 'tpope/vim-fireplace', { 'for': 'clojure' }
+
+" Unmanaged plugin (manually installed and updated)
+Plug '~/my-prototype-plugin'
+
+" Call plug#end to update &runtimepath and initialize the plugin system.
+" - It automatically executes `filetype plugin indent on` and `syntax enable`
+call plug#end()
+" You can revert the settings after the call like so:
+"   filetype indent off   " Disable file-type-specific indentation
+"   syntax off            " Disable syntax highlighting
+
+" Color schemes should be loaded after plug#end().
+" We prepend it with 'silent!' to ignore errors when it's not yet installed.
+silent! colorscheme seoul256
+```
+
+### Lua example for Neovim
+
+In Neovim, you can write your configuration in a Lua script file named
+`init.lua`. The following code is the Lua script equivalent to the Vim script
+example above.
+
+```lua
+local vim = vim
+local Plug = vim.fn['plug#']
+
+vim.call('plug#begin')
+
+-- Shorthand notation for GitHub; translates to https://github.com/junegunn/seoul256.vim.git
+Plug('junegunn/seoul256.vim')
+
+-- Any valid git URL is allowed
+Plug('https://github.com/junegunn/vim-easy-align.git')
+
+-- Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
+Plug('fatih/vim-go', { ['tag'] = '*' })
+
+-- Using a non-default branch
+Plug('neoclide/coc.nvim', { ['branch'] = 'release' })
+
+-- Use 'dir' option to install plugin in a non-default directory
+Plug('junegunn/fzf', { ['dir'] = '~/.fzf' })
+
+-- Post-update hook: run a shell command after installing or updating the plugin
+Plug('junegunn/fzf', { ['dir'] = '~/.fzf', ['do'] = './install --all' })
+
+-- Post-update hook can be a lambda expression
+Plug('junegunn/fzf', { ['do'] = function()
+  vim.fn['fzf#install']()
+end })
+
+-- If the vim plugin is in a subdirectory, use 'rtp' option to specify its path
+Plug('nsf/gocode', { ['rtp'] = 'vim' })
+
+-- On-demand loading: loaded when the specified command is executed
+Plug('preservim/nerdtree', { ['on'] = 'NERDTreeToggle' })
+
+-- On-demand loading: loaded when a file with a specific file type is opened
+Plug('tpope/vim-fireplace', { ['for'] = 'clojure' })
+
+-- Unmanaged plugin (manually installed and updated)
+Plug('~/my-prototype-plugin')
+
+vim.call('plug#end')
+
+-- Color schemes should be loaded after plug#end().

-### Example: A small [sensible](https://github.com/tpope/vim-sensible) Vim configuration
+## Post-update hooks
+
+There are some plugins that require extra steps after installation or update.
+In that case, use the `do` option to describe the task to be performed.
 
 ```vim
-call plug#begin()
+Plug 'Shougo/vimproc.vim', { 'do': 'make' }
-Plug 'tpope/vim-sensible'
+Plug 'ycm-core/YouCompleteMe', { 'do': './install.py' }
-call plug#end()
 ```
 
-### On-demand loading of plugins
+If the value starts with `:`, it will be recognized as a Vim command.
+
+```vim
+Plug 'fatih/vim-go', { 'do': ':GoInstallBinaries' }
+```
+
+To call a Vim function, you can pass a lambda expression like so:
+
+```vim
+Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
+```
+
+If you need more control, you can pass a reference to a Vim function that
+takes a dictionary argument.
+
+```vim
+function! BuildYCM(info)
+  " info is a dictionary with 3 fields
+  " - name:   name of the plugin
+  " - status: 'installed', 'updated', or 'unchanged'
+  " - force:  set on PlugInstall! or PlugUpdate!
+  if a:info.status == 'installed' || a:info.force
+    !./install.py
+  endif
+endfunction
+
+Plug 'ycm-core/YouCompleteMe', { 'do': function('BuildYCM') }
+```
+
+A post-update hook is executed inside the directory of the plugin and only run
+when the repository has changed, but you can force it to run unconditionally
+with the bang-versions of the commands: `PlugInstall!` and `PlugUpdate!`.
+
+> [!TIP]
+> Make sure to escape BARs and double-quotes when you write the `do` option
+> inline as they are mistakenly recognized as command separator or the start of
+> the trailing comment.
+>
+> ```vim
+> Plug 'junegunn/fzf', { 'do': 'yes \| ./install' }
+> ```
+>
+> But you can avoid the escaping if you extract the inline specification using a
+> variable (or any Vim script expression) as follows:
+>
+> ```vim
+> let g:fzf_install = 'yes | ./install'
+> Plug 'junegunn/fzf', { 'do': g:fzf_install }
+> ```
+
+### `PlugInstall!` and `PlugUpdate!`
+
+The installer takes the following steps when installing/updating a plugin:
+
+1. `git clone` or `git fetch` from its origin
+2. Check out branch, tag, or commit and optionally `git merge` remote branch
+3. If the plugin was updated (or installed for the first time)
+    1. Update submodules
+    2. Execute post-update hooks
+
+The commands with the `!` suffix ensure that all steps are run unconditionally.
+
+## On-demand loading of plugins
 
 ```vim
 " NERD tree will be loaded on the first invocation of NERDTreeToggle command
-Plug 'scrooloose/nerdtree', { 'on': 'NERDTreeToggle' }
+Plug 'preservim/nerdtree', { 'on': 'NERDTreeToggle' }

-### Dependency resolution
+> [!NOTE]
+> #### Should I set up on-demand loading?
+>
+> You probably don't need to.
+>
+> A properly implemented Vim plugin should already load lazily without any
+> help from a plugin manager (`:help autoload`). So there are few cases where
+> these options actually make much sense. Making a plugin load faster is
+> the responsibility of the plugin developer, not the user. If you find
+> a plugin that takes too long to load, consider opening an issue on the
+> plugin's issue tracker.
+>
+> Let me give you a perspective. The time it takes to load a plugin is usually
+> less than 2 or 3ms on modern computers. So unless you use a very large
+> number of plugins, you are unlikely to save more than 50ms. If you have
+> spent an hour carefully setting up the options to shave off 50ms, you
+> will have to start Vim 72,000 times just to break even. You should ask
+> yourself if that's a good investment of your time.
+>
+> Make sure that you're tackling the right problem by breaking down the
+> startup time of Vim using `--startuptime`.
+>
+> ```sh
+> vim --startuptime /tmp/log
+> ```
+>
+> On-demand loading should only be used as a last resort. It is basically
+> a hacky workaround and is not always guaranteed to work.
 
-See [Dependency
+> [!TIP]
-Resolution](https://github.com/junegunn/vim-plug/wiki/Dependency-Resolution).
+> You can pass an empty list to `on` or `for` option to disable the loading
+> of the plugin. You can manually load the plugin using `plug#load(NAMES...)`
+> function.

-### FAQ/Troubleshooting
+- [Jan Edmund Lazo](https://github.com/janlazo) - Windows support
+- [Jeremy Pallats](https://github.com/starcraftman) - Python installer
 
-#### Plugins are not installed/updated in parallel
+## License
-
-Your Vim does not support Ruby interface. `:echo has('ruby')` should print 1.
-In order to setup Vim with Ruby support, you may refer to [this
-article](http://junegunn.kr/2013/09/installing-vim-with-ruby-support).
-
-#### *Vim: Caught deadly signal SEGV*
-
-If your Vim crashes with the above message, first check if its Ruby interface is
-working correctly with the following command:
-
-```vim
-:ruby puts RUBY_VERSION
-```
-
-If Vim crashes even with this command, it is likely that Ruby interface is
-broken, and you have to rebuild Vim with a working version of Ruby.
-(`brew remove vim && brew install vim` or `./configure && make ...`)
-
-If you're on OS X, one possibility is that you had installed Vim with
-[Homebrew](http://brew.sh/) while using a Ruby installed with
-[RVM](http://rvm.io/) or [rbenv](https://github.com/sstephenson/rbenv) and later
-removed that version of Ruby.
-
-[Please let me know](https://github.com/junegunn/vim-plug/issues) if you can't
-resolve the problem. In the meantime, you can set `g:plug_threads` to 1, so that
-Ruby installer is not used at all.
-
-#### Errors on fish shell
-
-If vim-plug doesn't work correctly on fish shell, you might need to add `set
-shell=/bin/sh` to your .vimrc.
-
-Refer to the following links for the details:
-- http://badsimplicity.com/vim-fish-e484-cant-open-file-tmpvrdnvqe0-error/
-- https://github.com/junegunn/vim-plug/issues/12
-
-#### Freezing plugin version with commit hash
-
-vim-plug does not allow you to freeze the version of a plugin with its commit
-hash. This is by design. I don't believe a user of a plugin should be looking
-at its individual commits. Instead, one should be choosing the right version
-using release tags or versioned branches (e.g. 1.2.3, stable, devel, etc.)
-
-```vim
-Plug 'junegunn/vim-easy-align', '2.9.2'
-```
-
-If the repository doesn't come with such tags or branches, you should think of
-it as "unstable" or "in development", and always use its latest revision.
-
-If you really must choose a certain untagged revision, consider forking the
-repository.

+POST-UPDATE HOOKS                                       *plug-post-update-hooks*
+==============================================================================
+
+There are some plugins that require extra steps after installation or update.
+In that case, use the `do` option to describe the task to be performed.
+>
+    Plug 'Shougo/vimproc.vim', { 'do': 'make' }
+    Plug 'ycm-core/YouCompleteMe', { 'do': './install.py' }
+<
+If the value starts with `:`, it will be recognized as a Vim command.
+>
+    Plug 'fatih/vim-go', { 'do': ':GoInstallBinaries' }
+<
+To call a Vim function, you can pass a lambda expression like so:
+>
+    Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
+<
+If you need more control, you can pass a reference to a Vim function that
+takes a dictionary argument.
+>
+    function! BuildYCM(info)
+      " info is a dictionary with 3 fields
+      " - name:   name of the plugin
+      " - status: 'installed', 'updated', or 'unchanged'
+      " - force:  set on PlugInstall! or PlugUpdate!
+      if a:info.status == 'installed' || a:info.force
+        !./install.py
+      endif
+    endfunction
+
+    Plug 'ycm-core/YouCompleteMe', { 'do': function('BuildYCM') }
+<
+A post-update hook is executed inside the directory of the plugin and only run
+when the repository has changed, but you can force it to run unconditionally
+with the bang-versions of the commands: `PlugInstall!` and `PlugUpdate!`.
+
+[!TIP] Make sure to escape BARs and double-quotes when you write the `do`
+option inline as they are mistakenly recognized as command separator or the
+start of the trailing comment.
+>
+    Plug 'junegunn/fzf', { 'do': 'yes \| ./install' }
+<
+But you can avoid the escaping if you extract the inline specification using a
+variable (or any Vim script expression) as follows:
+>
+    let g:fzf_install = 'yes | ./install'
+    Plug 'junegunn/fzf', { 'do': g:fzf_install }
+<
+
+< PlugInstall! and PlugUpdate! >______________________________________________~
+                                                    *pluginstall-and-plugupdate*
+
+The installer takes the following steps when installing/updating a plugin:
+
+ 1. `git clone` or `git fetch` from its origin
+ 2. Check out branch, tag, or commit and optionally `git merge` remote branch
+ 3. If the plugin was updated (or installed for the first time)
+   1. Update submodules
+   2. Execute post-update hooks
+
+The commands with the `!` suffix ensure that all steps are run
+unconditionally.
+
+
+ON-DEMAND LOADING OF PLUGINS                 *plug-on-demand-loading-of-plugins*
+==============================================================================
+>
+    " NERD tree will be loaded on the first invocation of NERDTreeToggle command
+    Plug 'preservim/nerdtree', { 'on': 'NERDTreeToggle' }
+
+    " Multiple commands
+    Plug 'junegunn/vim-github-dashboard', { 'on': ['GHDashboard', 'GHActivity'] }
+
+    " Loaded when clojure file is opened
+    Plug 'tpope/vim-fireplace', { 'for': 'clojure' }
+
+    " Multiple file types
+    Plug 'kovisoft/paredit', { 'for': ['clojure', 'scheme'] }
+
+    " On-demand loading on both conditions
+    Plug 'junegunn/vader.vim',  { 'on': 'Vader', 'for': 'vader' }
+
+    " Code to execute when the plugin is lazily loaded on demand
+    Plug 'junegunn/goyo.vim', { 'for': 'markdown' }
+    autocmd! User goyo.vim echom 'Goyo is now loaded!'
+<
+[!NOTE] #### Should I set up on-demand loading?
+
+You probably don't need to.
+
+A properly implemented Vim plugin should already load lazily without any help
+from a plugin manager (`:help autoload`). So there are few cases where these
+options actually make much sense. Making a plugin load faster is the
+responsibility of the plugin developer, not the user. If you find a plugin
+that takes too long to load, consider opening an issue on the plugin's issue
+tracker.
+
+Let me give you a perspective. The time it takes to load a plugin is usually
+less than 2 or 3ms on modern computers. So unless you use a very large number
+of plugins, you are unlikely to save more than 50ms. If you have spent an hour
+carefully setting up the options to shave off 50ms, you will have to start Vim
+72,000 times just to break even. You should ask yourself if that's a good
+investment of your time.
+
+Make sure that you're tackling the right problem by breaking down the startup
+time of Vim using `--startuptime`.
+>
+    vim --startuptime /tmp/log
+<
+On-demand loading should only be used as a last resort. It is basically a
+hacky workaround and is not always guaranteed to work.
+
+                                                                     *plug#load*
+
+[!TIP] You can pass an empty list to `on` or `for` option to disable the
+loading of the plugin. You can manually load the plugin using
+`plug#load(NAMES...)` function.
+
