Fwd port: Do not output arguments from expression while evaluating them

forward port of 9adf51fd59eea6082a0aff8514bb633d7a6655c0
from old kde-runtime repo

Original commit text:
Do not output arguments from expression while evaluating them

Man pages contain macro calls with arguments, e.g.
.INDENT 0.0
(in cmake or in ktutil man pages)
The bug was with the evaluation of the argument of the macro, which
was printed while evaluating it, which should not be done.

BUG: 335169
