That works too.

I had a sort of vision of catching the "args..." notation that a lot of
kerneldoc comments use and doing the right thing, but ran out of patience
before getting it to work. There are times when I find Markus's python
kernel-doc replacement tempting... Maybe I'll beat my head against that
wall one more time when I get a chance and, failing that, just use the
above.

Thanks,
