Hmmm, come to think of it, if you are doing vanilla Celtk (not Cello) 
collapsed might not apply. I /think/ simply making, say, the middle 
widget of three invisible would cause it to be unpacked (there being no 
way to say "invisible" in Tk) and then packing would scrunch the ends 
together simply because there would be no middle.

Sorru for the headfake.
