Rigify: bug fix for biped arm/leg rigs.
The bbone elbow was causing weird twisting and sharp bend angles
even when smooth elbow/knee was fully disabled. Now fixed.
This fix, however, exposes bug #34532 in Blender, so for the time
being the transition between smooth/sharp elbow is a jumpy one.
This is less objectionable, however, then the weird twisting
that was happening, as bug #34532 can be worked around by the
animator, whereas the weird twisting could not be worked around.
