Hmm.  We already do that without your patch.

    $ git branch /foo//bar
    $ git for-each-ref --format='%(refname)'
    refs/heads/foo/bar
    refs/heads/master
    $ git branch -d /foo//bar
    Deleted branch /foo//bar (was deadbeef)
    $ git for-each-ref --format='%(refname)'
    refs/heads/master

Perhaps an interface to give a cleaned-up version, e.g.

    $ git check-ref-format --print refs/heads//foo/bar
    refs/heads/foo/bar

is what you want in order to fix git-gui?  I dunno.
