OK boys and girls.  It's stump-the-stars time again.

This one should be easy.

When a formal argument for a function-like macro is replaced (whilst a
macro call is being expanded) must (or may) the sequence of replacement
pp-tokens include leading and/or trailing whitespace if the corresponding
actual argument also contained leading or trailing whitespace (respectively)?

In other words, what should be the result of:

	#define PREFIX(x) prefix##x

	... PREFIX ( xxyyzz) ...
