I don't like a new field in struct Dwfl_Module that is only used for
this single thing. So if we can store the state somewhere else that
would be nice.

I see what you are saying can happen theoretically, but have a little
trouble imagining when this would every happen. If you are just using
parse_argp for command line parsing I don't really see how that would
happen. Are you thinking of some server program that would reuse
dwfl_standard_argp () multiple times?

Thanks,
