Good point.

I basically agree with Boyd, that if it can be done outside the shell,
it should.

I hope people can see how adding a feature because it makes things
faster could send one down the feeping creaturism road.

In David's case, it appears that repeated calls to "test" in a short
period of time are his problem.  The purpose of this is to determine
what to put in his path.  Perhaps in general, the overhead of calling
"test" is not usually a problem.

Perhaps, then, what he needs to do is create a utility which for each
directory name argument will check if the directory exists, and output
the name if it does.

Thus, setting his path simply becomes:

	path=`{$home/bin/exists $path thatdir theotherdir /usr/local}

and then only one "exec" is needed for this in his .rcrc.
