I tried using change-log-mode but it indented the whole commit 
message with 4 spaces when I used M-q on it. My current mode seems to do 
the job with M-q, I just didn't use it before (and it removes the : 
between lisp/autoinsert and (auto-insert-alist) which looks like the 
intended formatting since other commit logs are formatted this way).
