From: Junio C Hamano Date: Sat, 22 Dec 2012 08:33:30 GMT Subject: [PATCH 5/7] get_patch_filename(): drop "just-numbers" hack Message-ID: <1356165212-5611-6-git-send-email-gitster@pobox.com> In-Reply-To: <1356165212-5611-1-git-send-email-gitster@pobox.com> The function chooses from three operating modes (format using the subject, the commit, or just number) based on NULL-ness of two of its parameters, which is an ugly hack for sharing only a bit of code. Separate out the "just numbers" part out to the callers.
