On what systems is env located in /bin/env?  The normal location is in
/usr/bin/env.  I checked HP-UX, AIX, Solaris, FreeBSD, and various
GNU/Linux systems.  All had /usr/bin/env.  This is counted upon by
many scripts using /usr/bin/env as a launcher.  I would have said it
was a standard but upon a quick search I could not find a reference.

Yes, that will be nice.  But all of the problems with #! is why it is
well known as the "Berkeley hack".  Too useful to be without.  To ill
defined to be really portable.
