I'm afraid no, in 1.33.1. I was assuming that with unregistered option, user
has to do some manual word with basic_parsed_options object anyway (like
pass unregistered options to some other part of the program), so did not
paid attention to "store".

Now that you bring it up, it seems reasonable to ignore unregistered options
in "store". A change and a testcase to that effect are just committed.

If you don't want to use CVS version, you can just add

            if (options.options[i].unregistered)

to the loop in the store function.
