trace +key,+keyboard (+more) when typing keys c, shift left, left

The attached traces shows how on the Mac, XmbLookupString returns a string (+ a
keysym). On Linux it does not.
This is somewhat odd, I didn't notice it when using xev. Maybe this depends on
the XIC input context?

keyboard:X11DRV_ToUnicodeEx Found keycode 78 (0x4E)
key:X11DRV_ToUnicodeEx type 2, window e00005, state 0x0001, keycode 0x004e
keyboard:X11DRV_ToUnicodeEx XmbLookupString needs 1 byte(s)
key:X11DRV_ToUnicodeEx nbyte = 1, status 0x4
key:X11DRV_ToUnicodeEx KeyPress : keysym=2B (plus), # of chars=1 / "+"

winex11.drv/keyboard.c:X11DRV_ToUnicodeEx has a comment on th5s:
        /* We have a special case to handle : Shift + arrow, shift + home, ...
           X returns a char for it, but Windows doesn't. Let's eat it. */
            && (keysym>=XK_KP_0) && (keysym<=XK_KP_9))
B4t that code only handles KP_0 to KP_9, not the arrow keys.
