Subject: [PATCH 09/15] refs.c: only write reflog update if msg is non-NULL
Date: Wed, 23 Jul 2014 10:03:49 -0700	[thread overview]
Message-ID: <1406135035-26441-10-git-send-email-sahlberg@google.com> (raw)
In-Reply-To: <1406135035-26441-1-git-send-email-sahlberg@google.com>

When performing a reflog transaction update, only write to the reflog iff
msg is non-NULL. This can then be combined with REFLOG_TRUNCATE to perform
an update that only truncates but does not write.
