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.
This is my personal oh-my-zsh theme. It has Git support through
methods found in Git lib file of oh-my-zsh. It uses:
- parse_git_dirty()
- git_prompt_ahead()
- current_branch()
- git_prompt_short_sha()
- git_prompt_status()
It also shows user name, machine name and current path. You can
