1. Run xkbwatch.
2. Press and hold:
	right shift
	right control
	fn
	left alt
	left shift
3. Release:
	right shift
	right control
	fn
	left alt
	left shift

I expect no "LEDs" to remain on.  Instead, the first and third from
the right in the first, fourth, and fifth groups of LEDs remain on.

 [ ][ ][ ][ ][ ][#][ ][#]
	[ ][ ][ ][ ][ ][ ][ ][ ] \
	[ ][ ][ ][ ][ ][ ][ ][ ] \

Tapping various modifiers eventually clears the LEDs.

Reproducible with xev so I suppose it is not an Xt bug.  I doubt this
is a libx11 bug, either, but one has to start somewhere.  I don't
think this is a regression, since it's been happening for a while.

Ideas?
