# Effect: sets $PS1 to show git branch, dirty and stash status.
# Stash skipped in cygwin as it was too slow when tested, YMMV.

# To insert the git smarts into your own PS1, add this:
# $(git branch &>/dev/null;if [ $? -eq 0 ]; then echo " $(parse_git_branch)$(parse_git_dirty)$(parse_git_stash)"; fi)
