Subject: [PATCH] snippets: Harden for review activity.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When reviewing patches, whose commit logs don't follow the structure outlined
in “Submitting Patches”, a reviewer might be tempted to use snippets to
rewrite them.  This makes it so that their attempt, while not immediately
succeeding, isn't completely thwarted.

* etc/snippets/tempel/text-mode (add\ , remove\ , rename\ , update\ )
(addcl\ , https\ ): Use an empty "p" field if (car (magit-staged-files))
fails.
