Thank you very much. I think that adding a new function is preferrable
in this case because we are adding significant new functionality (by the
positional arguments handling). We should leave the old fmtcheck(3) alone
(so that existing code does not break) and just document its deficiencies
and say to use fmtmatch(3) instead.

Best,
