Yes, this does work; I should have mentioned that I'd found it. It wasn't
in the Gtk-- interface but I added it and am happier. It would be nice to
have the equivalent for GtkMenu (that's so easy to write I might do so
instead of whining. :-) However GtkMenu only uses the index for set_active
and insert; both of those could simply have versions that took a pointer
instead, I think that would be more convenient. 

However, this doesn't solve the reverse mapping problem; created, for
example, by gtk_notebook_current_page(), which returns an index. This is
so easy to solve I already sent in a several-line patch. ;-)
