Surprise, surprise, this is actually ambiguous. When I first read
this I assumed it meant `text inside a string or character constant
anywhere'. It really means `text inside a string or character
constant (except in the replacement portion of a macro)'.
Unfortunately the former is the more reasonable interpretation
(naturally---it is mine :-) ), so the ANSI standard has settled on
that, and introduces some new `experimental' `stringizing' macro
expansion features.
