Nowadays, in case of author != commiter, we don't write down the name of
committer in ChangeLog.  Any reason you do so?  I noticed that you did
this in several Tristan's patches.

It's something I have been doing on occasions. The idea was that
people working from source packages alone could see who did the push.
But I'm not really attached to it, so this can be skipped if people
prefer.

The GNU coding standards has section saying not to do that.  From
<https://www.gnu.org/prep/standards/standards.html>:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When you install someone else’s changes, put the contributor’s name in the change
log entry rather than in the text of the entry. In other words, write this:

2002-07-14  John Doe  <jdoe@gnu.org>

        * sewing.c: Make it sew.

rather than this:

2002-07-14  Usual Maintainer  <usual@gnu.org>

        * sewing.c: Make it sew.  Patch by jdoe@gnu.org.

As for the date, that should be the date you applied the change. 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Thanks,
