engine: Ctrl+Shift chords belong to the application

Ctrl+Shift+V switched to Vietnamese and ate the key, in every terminal
where it pastes; Ctrl+Shift+T and N opened no tab.  Only a plain
Ctrl+letter is a strans command now; a chord with Shift, Alt, or Super
commits what is pending and passes, as Alt and Super chords already did.
Caps Lock still works: the keysym's case never mattered.
