Shamus:
This construct is meant to deal with nested macros, so the simple minded way
we deal with them now won't work. :-/ Have to think about how to fix.
-What we could do is simply move the argp with each call, and move it back by the
-number of arguments in the macro that's ending. That would solve the problem nicely.

[Which we do now. But that uncovered another problem: the token strings are all
-stale by the time a nested macro gets to the end. But they're supposed to be symbols,
-which means if we put symbol references into the argument token streams, we can
-alleviate this problem.]
