Not many, but some rather straight-forward ones. E.g.

	# quoted to preserve tabs & newslines (Windows users are creative)
	gitdir="$(git rev-parse --git-dir)"
	case "$gitdir" in
	[A-Za-z]:*)
		gitdir="/${gitdir%%:*}${gitdir#?:}"
		;;
	esac

Note: untested.

Note2: I did not add error handling, either.

Note3: yes, ${...} is available in bash and it does not fork. Neither does
       case ... esac

Ciao, Johannes
