Subject: [PATCH v2 08/18] do_for_each_reflog(): use a strbuf to hold logfile name
Date: Fri, 27 Apr 2012 00:26:57 +0200 [thread overview]
Message-ID: <1335479227-7877-9-git-send-email-mhagger@alum.mit.edu> (raw)
In-Reply-To: <1335479227-7877-1-git-send-email-mhagger@alum.mit.edu>
From: Michael Haggerty <mhagger@alum.mit.edu>
This simplifies the bookkeeping and allows an (artificial) restriction
on refname component length to be removed.
