    Fix handling of shifted SCO function keys.
    
    A user points out that this has regressed since 0.76, probably when I
    reorganised the keyboard control-sequence formatting into centralised
    helper functions in terminal.c.
    
    The SCO function keys should behave differently when you press Shift
    or Ctrl or both. For example, F1 should generate ESC[M bare, ESC[Y
    with Shift, Esc[k with Ctrl, Esc[w with Shift+Ctrl. But in fact, Shift
    was having no effect, so those tests would give ESC[M twice and ESC[k
    twice.
    
    That was because I was setting 'shift = false' for all function key
    types except FUNKY_XTERM_216, after modifying the derived 'index'
    value. But the SCO branch of the code doesn't use 'index' (it wouldn't
    have the right value in any case), so the sole effect was to forget
    about Shift. Easily fixed by disabling that branch for FUNKY_SCO too.
