Ooo, ick. I'll look into that. There's plenty of code in LDAO that does
substitutions like tabs to blanks and CRs to CRLFs, but I don't remember
doing anything with commas. And I usually pass code around in text
buffers, not using the inherent I/O routines to parse. Hmm.

"Needed" might be too strong. It's a stylistic thing. I feel that the
convex orientation is easier to work with, for two reasons:
a. it's self-documenting. In the convex orientation, it's fairly easy to
see that the object is a section of a sphere.
b. most of the time, part-authors will use it in a convex mode. Even most
interior corners will require a convex orientation.
