- Display load status
- Load plugin with 'L' key

(This commit also allows not loading a plugin with `'for': []`. It used
to load ftdetect files.)

-### Plugin directory
-
-If you omit the path argument to `plug#begin()`, plugins are installed in
-`plugged` directory under the first path in `runtimepath` at the point when
-`plug#begin()` is called. This is usually `~/.vim/plugged` (or
-`$HOME/vimfiles/plugged` on Windows) given that you didn't touch runtimepath
-before the call.

-### Dependency resolution
+### Post-update hooks
 
-See [Dependency
-Resolution](https://github.com/junegunn/vim-plug/wiki/Dependency-Resolution).
+There are some plugins that require extra steps after installation or update.
+In that case, use `do` option to describe the task to be performed.
+
+```vim
+Plug 'Valloric/YouCompleteMe', { 'do': './install.sh' }
+```
+
+If you need more control, you can pass a reference to a Vim function that
+takes a single 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.sh
+  endif
+endfunction
+
+Plug 'Valloric/YouCompleteMe', { 'do': function('BuildYCM') }
+```
+
+Both forms of post-update hook are 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!`.
+
+Make sure to escape BARs and double-quotes when you write `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 Vimscript expression) as follows:
+
+```vim
+let g:fzf_install = 'yes | ./install'
+Plug 'junegunn/fzf', { 'do': g:fzf_install }
+```

-### FAQ/Troubleshooting
+### License
 
-#### Plugins are not installed/updated in parallel
-
-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.
-
-### Regarding feature request
-
-You may submit a request for a new feature by [creating an
-issue](https://github.com/junegunn/vim-plug/issues). However, please be minded
-that this is an opinionated software and I want to keep the feature set as small
-as possible. So I may not agree with you on the necessity of the suggested
-feature. If that happens, I suggest the following options.
-
-1. Check out [Vundle](https://github.com/gmarik/vundle) or
-   [NeoBundle](https://github.com/Shougo/neobundle.vim).
-   They offer broader feature sets.
-2. Create a fork of this project and let it be your own plugin manager.
-   There's no need for us to have a single canonical branch.
