More complex programs may employ dispatch from the main program to subprograms
that do option parsing on their own. (I've written such programs before.) But
this is a rare use case, and even then I still don't see the use of globals in
getopt() being an actual problem, so I agree with you that we can probably
leave this bug closed.

I just disagree that it's "vague". :-)
