Yes, but this part could (and probably should) be moved to after the
'return', because default_face is not used before that.

There's no special significance to the _OR_NULL bit in this case.  If
we moved that part to after the 'return', we should probably use
FACE_FROM_ID instead, as the face pointer is actually dereferenced.
