Thanks, pushed to master.

Btw, your email client wraps lines, so the patch didn't apply, and I
had to do it manually.  Perhaps you should send patches as
attachments.

Also, please see how I formatted the log message, and do the same in
the future.  In particular, quite a few of your changes were never
mentioned in your log message.
