[PATCH 4/7] strbuf_branchname(): a wrapper for branch name shorthands

From
Junio C Hamano <gitster@pobox.com>
Date
Mar 21, 2009, 22:13 UTC
Message-ID
<1237673619-12608-5-git-send-email-gitster@pobox.com>
In-Reply-To
<1237673619-12608-4-git-send-email-gitster@pobox.com>

The function takes a user-supplied string that is supposed to be a branch name, and puts it in a strbuf after expanding possible shorthand notation. This removes repeated lines to do so in existing code.
