Re: [PATCH 1/2] parse_options: Add flag to prevent errors for further processing

Now I'm confused: my understanding is that the diff option parser just
leaves unrecognized stuff in argv. But isn't that what a
PARSE_OPTIONS_IGNORE_UNKNOWN flag would do, and isn't that wrong?

I was thinking more about the way how the lower level diff_opt_parse()
works by letting the caller to handle things that it itself does not know
how.

But I say this because I am not interested in "-a -b -c <=> -abc" and
haven't thought about how you would go about parsing something like that
sanely with partial knowledge.
