Thanks, I pushed this.

The log message was mis-formatted, which required me to tediously fix
it by hand.  Please in the future format the entries using "C-x 4 a"
or similar commands, to avoid that, okay?  In particular, lines longer
than 78 characters abort "git am", so please verify this doesn't
happen in the patches you submit.  "C-x 4 a" and friends format the
entries with leading TABs which you can later remove with "C-x TAB",
and that produces the optimal results, including when the log messages
are later used to generate ChangeLog files in the release tarballs.
