I like this one, for simplicity and obvious correctness alone, but will
defer to Eric for the final decision.  Question is whether the "then"
and "elif" parts should receive the same treatment.

BTW, m4_normalize would have been wrong as it can change expanded text
that you wouldn't want changed, too.  (I think.)

Cheers,
Ralf
