Except this. The wildmatch uses the same idiom, and I think it makes
sense. 1 = true, 0 = false, not 0 = exit zero, 1 = exit nonzero, which
would also be IMO a bit more confusing since it should really be 0 and
!0 if you don't want to rely on specific non-zero exit codes, which is
just going down a garden path of complexity when all we wanted was
"does this match".
