Yes, that could be done. Actually it would simplify the parser for
bicubic patch.

I'm not even sure why an extra comma explicitly forbidden - it's rather
unusual style in POV-Ray. Maybe it was implemented before commas were
made always optional, or the person implementing this piece of the
parser didn't know that.

I'm also looking at the matrix syntax while I'm at it.
