Fixes #4085: core -> plugin dependency issue.
Rename it to git_current_branch for clarity that it's git-specific.
Update all plugins that were calling it to use new name.
Fix variable leaks by making more variables in lib/git.zsh local.
Have lib/git.zsh use [[ ]] instead of [ ] everywhere.

add git alias `gcam` -  `git commit -am`

see
https://github.com/robbyrussell/oh-my-zsh/pull/2790#issuecomment-112716330

Current `ggpush` is `git push origin` instead of `git push origin $(current_branch)`
Same for `ggpull`

gaa was brought back by popular demand — see #3535
gap was replaced with gapa — see #3682
gdc was replaced with gdca — see #3977

also allow multiple arguments for ggp and ggl aliases

because it leaked, and led to #3991

because git rm will fail when no files were deleted

due to issues like #3962
until a proper plugin-loading system is implemented

by popular demand, see #3972

Fix typo: gm -> gmt

Add decorate and color to the normal oneline and add a new alias for graph oneline logs.

add command to ignore changes to file temporarily

I noticed that the function ``work_in_progress``, which is used in the "gallois"-theme, would print ``fatal: bad default revision 'HEAD'`` in a new folder after ``git init``.

This is the fix.
