Subject: scanner: Allow "--" as option argument.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e7d45afc6aeb49745f17d21ddba4848e0c0118fc;p=flex

scanner: Allow "--" as option argument.

Previously, invocations such as:

    flex --outfile -- wc1.l

 would fail with "requires an
argument" error message.

Fixes #285
