[colorforth] ?dup

["Chuck Moore" <chipchuck@xxxxxxxxxxxxxx>]

I agree that redefining standard Forth words is bad practice. But that's
just one consideration, and in the heat of the moment can get overlooked.

Perhaps the optimizing word  ?dup  could be renamed  /dup . The original
mnemonic intention was: is a  dup  necessary? The new mnemonic would be:
cancel  dup  if possible.

That is, if present use isn't entrenched?
