I put them in the manual because I said that I would. I can't speak for
everyone, but sometimes stuff like that is nice to have in the manual. I
don't often discover variables via custom, but that might be because I
generally have a specific thing I have in mind I want to change when I
use it.

Such a thing definitely should be mentioned in the docstrings for the
functions, which I entirely forgot to write in both this patch and the
last patch. Oops. Here's a rough patch for that.

I think if anything else, that putting a couple of mentions in the
docstrings of some of the entry point functions is a reasonable
compromise.

Thanks,
