I'm moving some functionality out of flx and lib/std/felix into class System
and class Shell,
in include std/system.flx and std/shell.flx.
There's some overlap between these classes. System traditionally
contains system(), exit(), argv() etc.
My concept for Shell is quoting and callouts to the shell, so Shell has
the real system command, and System just dispatches to it.
Shell also has
gen get_stdout: string -> int * string;
which is a wrapper around popen.
On the other hand System now gets
proc pexit: int
which is like exit but prints a diagnostic and can fixup
the exit code from a shell command.
Flx uses pexit so we know WHY something broke.
