Hmmh, the above Parse_Uline() runs properly if the Gtk.Label is created
separately, and then added to the menu item, but raises an exception if
it was created implicitly. Strange.

Criminy! Separately created labels display underlined characters okay in
menus, but the drop-down menu-items are all center-justified, and
there's _no_ way to left-justify them again (left-justify has no effect
unless the text is wider than the label and carries over to the next
line)! How stupid is _that_? Worse, the hints for the regular keyboard
shortcuts have disappeared! Arrgghhh!!!

I expected a steep learning curve, but this is ridiculous! There's one
thing left to try, an item factory. If that doesn't work, then I give up
on underlined menu shortcuts. If it weren't that C/C++ gives me hives,
I'd almost consider just using that instead of Ada for this project.
Yeesh!
