\BUGS: you can't do `which foo`

...which I do quite often.  Not nice.
Another bug: root possibly gets wrong answers (see which.c v3.0).
Furthermore you didn't include a `-a' option and you don't print the PATH
if there are no arguments.  Lastly your script is csh- and alias-oriented:
e.g. you don't support shell functions.
I think I stick with which.c.
