I've just implemented a new variable modifier in make(1), namely, :U.
Loosely speaking, this does a uniq on the variable's words, much as one
can say that :O does a sort on them.  (Normally, one would use :O:U, to
sort and then drop duplicates, but this doesn't have to be so.)  I did
this because I found a need for it.

I'm writing here to solicit comments on whether this would be a Good
Thing to have in the main tree.  Thoughts?
