That is a very different issue...  I do remember that debate, and in
fact I was in the thick of it.  It's just that I didn't have much
spare time to write up code for an alternate solution at the time.
Maybe someday I'll get back to that.  We *use* an alternate solution
for that issue here at RPI (instead of using `env' for it), so I know
other solutions are workable.

Sure it is.  My understanding is that you want to do something like:

#!/usr/local/bin/php -n -q -dsafe_mode=0 -doutput_buffering=1

With my new `env' in place, that line becomes:

#!/usr/bin/env -S/usr/local/bin/php -n -q -dsafe_mode=0 -doutput_buffering=1

The setting of PATH is irrelevant -- or at least it is no more
important than it had been with the previous setup.  You were
never *required* to use an unqualified filename with `env'.  That
is the example you see the most, but only because people *want*
to use `env' just so that they *can* get `perl' from the PATH.
