" value is `git`, the following plugins are supported: `gina`, `fugitive` and
" `gita`.
" >
"   [[layers]]
"     name = 'git'
"     git_plugin = 'git'
" <
" `git_diff_position`: set the default command to split diff windows, by
" default it is `10split`. Example:
" >
"   [[layers]]
"     name = 'git'
"     git_diff_position = 'vsplit'
" <
" @subsection Key bindings
"
" The following key bindings will be definded when the `git` layer is loaded.
" >
"   Key Binding   Description
"   SPC g s       view git status
"   SPC g S       stage current file
"   SPC g U       unstage current file
"   SPC g c       edit git commit
"   SPC g p       git push
"   SPC g m       git branch manager
"   SPC g d       view git diff
"   SPC g A       stage all files
"   SPC g b       open git blame windows
"   SPC g h a     stage current hunk
"   SPC g h r     undo cursor hunk
"   SPC g h v     preview cursor hunk
" <
" @subsection commit omni function
" This layer also provides an omnifunc for git commit messages. It supports:
" 1. complete commit title, `fix:`, `doc:` etc.
" 2. complete github issue list
