These lines are too long, please wrap them to make them shorter,
preferably no more than 75 characters.

Please also provide a ChangeLog style commit log message, as described
in CONTRIBUTE, and please mention the bug number there.

And finally, this new command needs to be mentioned in NEWS, under
"Python mode".

Thanks.

Thanks, I pushed this, and I'm closing the bug report.

A few minor tweaks were still needed, please see the actual commit for
what I needed to change, and try to avoid these gotchas in the future.

Also, the patch didn't apply automatically due to some lines being
wrapped by your email client; please either change your MUA or send
patches as attachments in the future.
