Why not recognize it all ways:
0 FACE ACW
0 FACE ANTICLOCKWISE
0 FACE CCW
0 FACE CLOCKWISE
0 FACE COUNTERCLOCKWISE
0 FACE CW
0 FACE DOUBLESIDED
0 FACE DS
0 FACE UNKNOWN
This adds a bit to the parser, but not so much.
The recommended standard for primitives, parts, and subparts should be the
short versions:
0 FACE CCW
0 FACE CW
0 FACE DS
0 FACE UNKNOWN
I didn't list a short version for 0 FACE UNKNOWN because (a) it won't be
used often, after a possible file-fixing transition period, and (b) it's
somewhat anamolous, and should be clearly marked.
