A regression was introduced by bdebec4e2e.
The intention of the change was to avoid using Qt's shortcut mechanism
to trigger menu items which were already triggered through the regular
menu API in Cocoa. However, Cocoa has trouble with key equivalents that
do not have any keyboard modifiers. Thus, we have to allow these
particular key sequences to go through the regular system. I've verified
that the original bug is still fixed with this change.
[ChangeLog][OS X] Fixed menu item shortcuts without keyboard
modifiers.
