Shortcuts: Shift+Comma and Shift+Period follow their key positions only with Shift alone

The key-position match for Shift+Comma and Shift+Period now applies only
when Shift is the only modifier. Cmd/Ctrl+Shift and Alt+Shift presses at
those keys keep their logical key, so the type-size shortcuts on German-like
layouts behave as before. The typing test also checks that no paint command
runs while text is edited.
