If the workaround in issue #43 is used along with the define of
STRIP_FLAG_HELP to 1, there would be a wrong "No modules matched"
message been print at end of the usage message.

That's because we continue the loop if we see strip flag help value and
never set the `found_match` flag to true even if we found a match.

By moving the set statement above the continue, we can avoid this wrong
message.
