Gotta love distributed work. Already committed in upstream. (I haven't checked it works but anyway there is a commit in the right file.)
So this (eventually) needs a new Maxima package and a doctest.

I think you might have done this at a weird time of day :) but this is correct, anyway, so I'll be sure to give this positive review once the branch looks right. Thanks!
