needs_string_links and need_extra_options

[adegroote]

It is not very clear from the documentation that one needs to add an extra entry in need_extra_options to have need_string_links works properly. Maybe it would be nice to have a cross-check that options referenced in needs_string_links needs to explictly exists in need_extra_options. Or at least, document it more explicitly.

Good point, the documentation and especially a check for this is missing.

Thanks for reporting this. :+1:
