whitespace before "-" ?

Ahhh materials. Quite a blast from the past :-).
I faintly remember them causing nothing but problems for some old radeon
chips (r100, maybe r200 IIRC) - or rather the ability to being able to
change them even between begin/end...
I could certainly see tons of things going wrong with them not just
between begin/end but additionally in a display list...
