[PATCH] Added a new placeholder '%cm' for full commit message

 Hello,

 I have added a new placeholder '%cm' for a full commit message. I made
 it because I want to use my own pretty format which currently only
 allows '%s' for subject and '%b' for body. But '%b' is substituted with
 <undefined> if the body is "missing" which I obviously don't like :)

 Thanks for consideration,
                        Michal
