[PATCH v2 04/18] get_ref_dir(): require that the dirname argument ends in '/'

From
mhagger@alum.mit.edu <mhagger@alum.mit.edu>

Message-ID
<1335479227-7877-5-git-send-email-mhagger@alum.mit.edu>
In-Reply-To
<1335479227-7877-1-git-send-email-mhagger@alum.mit.edu>
From: Michael Haggerty <mhagger@alum.mit.edu>

This removes some conditional code and makes it consistent with the way that direntry names are stored. Please note that this function is never used on the top-level .git directory; it is always called for directories at level .git/refs or deeper.
