[PATCH] gitlog-to-changelog: support the log message format used in Bison

[Akim Demaille]

Hi!

In Bison we have chosen to leave git cherry-pick additions
in the log messages.

Beside for a while I have been using a git log format that
is not expected by git-log-to-ChangeLog: the "* file: change."
section is tab-indented as in a ChangeLog.

This is an example of such an git log message:

commit a34e8b242e424545eee0411c7fad2715a2cc7230
Author: Akim Demaille <address@hidden>
Date:   Mon Feb 13 13:39:23 2012 +0100

    maint: add license headers.
    
        * examples/calc++/test, examples/variant.yy, AUTHORS, THANKS,
        * tests/atlocal.in, tests/bison.in: Add license headers.
        Reported by Tys Lefering.
    (cherry picked from commit 3272a7256f893399bbbc4b84e6181c71002f3fd8)
    
    Conflicts:
    
        examples/variant.yy
        tests/bison.in

This ends in a ChangeLog that is quite ugly.  The attached
patch results in the following diff on Bison's generated ChangeLog.
