    cellrendereraccel: don't translate Alt+Print to SysRq
    
    We want to use Alt+Print for screenshot keybindings, so we have to avoid
    translating it into SysRq, since that's what the keymap would dictate.
    After talking with Owen, it sounds like doing this generically would be
    a lot of work and quite hairy code, so hardcoding this should be OK.
