bug#33468: A bug with yes and --help

[Paul Eggert]

I'd rather see a function than a big macro like that. Can we do it as a 
function instead?

Is the idea to deprecate and/or stop using parse_long_options, since it 
doesn't work the way the Gnu Coding Standards says it should? If so, 
maybe it would be simpler to change parse_long_options instead. This 
could involve changing the API for parse_long_options.
