with the state of modern shells (zsh, bash, sh, ksh, tcsh, csh, etc...)
and the number of them that do things differently, i think you deserve
to lose if you're using a shell that does aliases (ala bash for example)
and then use /usr/bin/which.  all shells that have aliases (thereby
confuscating the path search as far as normal processing goes) should
all have a which builtin.  i believe most already do.  but for those
that don't have aliasing, a *BINARY* /usr/bin/which that just searches
using the PATH environment variable should be *fine*.  why isn't this
replaced?  why hasn't it been already (imho)?
