I didn't know about "\s", but you do need the '^' at the start or
it picks up other uses of "-t". Those only happen after the
definition of "-t" but that's not the case for other arguments like
"-r" which are used before the definition.
But I see it doesn't work for "-r" anyway because that's defined
with square brakets for the optional stream specifier:
-r[:stream_specifier] fps (input/output,per-stream)
If the regex parser supports OR with "\|" I think you could handle
that without picking up likely uses of "-r" elsewhere in the text,
but it's not working for me. It always takes me about ten attempts
to get a regex that complex to work though. In any case you need
something smarter that looks at the formatting properly, and
ideally makes an index that can be browsed interactively.
