I don't agree that they are really distinct key combinations, but lets
table that argument.
I do think that control is insufficiently special to deserve a special
case. There should be one (and preferably only one) way to spell control.
QT, for example, does have separate "key" and "modifiers", but it always
spells control Key_Control. Furthermore, we define a order for modifier
keys (ctrl, alt, super), unless control happens to be hit last (though
probably backend dependent) and if there are only modifier keys pressed.
If someone actually wanted to use key_press_event-s in a significant way,
they are going to have to reverse engineer all of these quirks. That seems
silly.
