Whitespace separates parameters, not just comma, so I don't
think that'd be disambiguating.  I stand by my position that
allowing other than alphanumerics + _ in macro parameter names
is a walk down the wrong lane.  The powerpc symbol issue seems
to support that position.

(BTW, I agree with davem that your overlong lines makes
communication harder.)
