You don't need the "Change Log: 2016-11-27 Christopher R. Genovese
<genovese@cmu.edu>" part, that information is extracted automatically
from the commit metadata.

By "drop" I hope you meant "replaced it with `_'".  The action function
receives 1 argument, so it has to accept it.

I don't really agree with this switching *Warnings* to help-mode.
First, it's out of place for a particular warning to start manipulating
the *Warnings* buffer like that.  And second, it would make more sense
to have a warnings-mode, that could provide more specialized bindings
(e.g., ignore warning at point).  But that's a subject for another
thread.  I don't think this patch should do anything about it.
