[gtkmm] Overriding/correcting automatically generated API documentation

[Matthew Walton <matthew alledora co uk>]

I've managed to fix Gtk::FileChooser so that get_uris() returns an 
SListHandle<Glib::ustring> instead of a GSList *, and this appears to 
work quite nicely. However, the documentation generated for it refers to 
it returning a G::SList * - as does the documentation for 
FileChooser::get_filenames(), which also returns an SListHandle. How 
should I go about persuading gmmproc to give me the right documentation? 
Do I have to abandon use of _WRAP_METHOD and write these methods 
manually, or is there another way to do it?

I looked in the hg files this morning and couldn't find any examples of 
anything that looked like documentation being altered for methods 
wrapped with _WRAP_METHOD, only for ones which were wrapped by hand.

Regards
