I am doing something wrong or is it a bug. Just not yet done .. coloring such math thingies is somewhat tricky ... added. > 2.

I'll add \mskip\thinmuskip around the middle ... no clue what key/value to use so we can wait tile someone compliants > 3. Finally, why are the default values of left, middle, and right = > 0x2E. Isn't 0x7C a better default? Well, the period is (for tex) special in the sense that it is a nop so if you only want ( and no ) then explaining to a user that a period is to be used to nil the right symbol is somewhat less troublesome. One sets up the wanted symbols anyway.
