Hmm, so
--foo=bar
returns POPT_ERROR_UNWANTEDARG but
--foo bar
returns bar in the argument list?
The other way to "fix" the error is to morph "--foo=bar"
behavior to be identical to "--foo bar", i.e. an extra
argument failure.
Lemme muddle a bit about whether the two forms should be
treated differently or identically, that's purely a design
issue.
Both cases are an error no matter what. There's
nothing wrong with your patch whatsoever, just that it
introduces instant legacy incompatibility. *shrug*
Thanks for the patch.

Anything you want to see in POPT 2.0? I'm collecting features ...
