[PATCH] new-workdir: handle rev-parse --git-dir not always giving full path

rev-parse --git-dir outputs a full path - except for the single case
of when the path would be $(pwd)/.git, in which case it outputs simply
.git.  Check for this special case and handle it.

I tried to use new-workdir yesterday for the first time in a while, and found that it worked provided I gave a path inside the base repo, but not the path of the repo itself.

Turns out to be an oddity in rev-parse --git-dir output.  Since the rev-parse code explicitly does something different, I assume there is a reason for it.
