Replying to myself.

Regardless of "'refs/heads/$branch' is not found because we do not look
for in the right place" issue, shouldn't the use of the --mirror without
the --bare option forbidden or at least warned about?

Cloning as --mirror, with a working tree with a current branch, would mean
the next fetch would directly try to update it by overwriting.  We do pass
the --update-head-ok from pull, so "git pull" in such a repository should
be "sort of" safe, as long as the repository is never used to create its
own commits on whatever local branches set to be overwritten by --mirror,
but still I have this gut feeling that such an arrangement should at least
be discouraged.

Comments and/or opinions?
