The documentation says the actions supported by _regex_arguments are the
same as those supported by _arguments, although I didn't try it; in nay
case I don't see why you shouldn't use a function to complete for the
context, either.

You'll probably need to make _regex_arguments skip up to the last comma,
so you don't need to figure out a valid last of values until you know
you're trying to complete one.  I think _ip does that sort of thing.
