[git-new-workdir RFC] Backlinking $workdir/logs/HEAD to $GIT_DIR/logs/workdir?

Hello,

I use git new-workdir for some of my projects. Apart from the usual caveat "don't checkout the same branch twice", I found another small issue, surely known: the reflog for HEAD in the workidirs does not exist in the source git repo, hence git-gc will happily prune what it believes to be dangling commits.

Would it be, perhaps, be okay to create a logs/workdir/<name>/HEAD symlink pointing to $workdir/logs/HEAD, so that this does not happen?

Comments welcome.
