OK. Maybe I did go overboard with the second parameter thing. Still, there
should be a way to embed the value of an environmental variable into the
path (or URI), or any of the argument values. ANY way.

And now that I think about it, using a file path in COMMAND may not be a bad
idea exactly because environment variables would store paths in the OS'
format.

The best way I think may be to allow both. That is, first check if the value
is a valid URI, and resolve it to the proper file path if it is, otherwise,
cast it on the interpreter as is.

In my opinion, the cost-benefit on this has gotten out of hand --
designing ways to mess about with environment variables which
reproduce the complexities of the union of all the likely
platforms. . .  Just say 'no'!

Having said that, the documentation probably does need to say
_something_ about environment variables, even if it's no more than "It
is implementation-defined what environment variables, if any, are
passed down."  I know from bitter experience that if steps are _not_
taken to pass the SYSTEMROOT env. var. when running on Windoz OSes
then obscure failures result. . .
