Initial release for this fork.
This is a fork from the original git-sh repository at https://github.com/rtomayko/git-sh
What this fork has different is:
- mv and rm aren't aliased to git command
- improved documentation: color.sh.upstream-state is documented in README.markdown
- add 'git flow' support from taupecat@9f69608
- add 'git worktree' support from https://github.com/selivan/git-sh
- this README is updated (to show this Fork information section, also the Installation points to this repository)
