True, but it still bothers me a bit.  (I don't know whether the "w"
stands for "word" or "white space".  :-)

Also, will we need "_w" variants for other macros?  If so, I'd rather
not maintain/describe pairs of macros, and it'd be better to factor
out only the m4_split(m4_normalize([$1])) idiom rather than the
m4_foreach(..., m4_split(m4_normalize([$1])), ...) idiom.
