Yes, that’s a good point; that should work (the ECL issue should be the same as this).
But: I think I just understood what the problem is:
The function %normalize-system-command is used in two places:
(1) in %system when launch-program is used and
(2) in %redirected-system-command, which is called from %system if launch-program is not used
The fact that both paths use the same function is actually suboptimal. Because in case (2), %redirected-system-command builds a large string out of what %normalize-system-command returns (it expects a string and adds to it), for (1) it would be much nicer if a list was returned, namely (“sh” “-c” …) or (“cmd” “/c” …) because that could be fed into launch-program as-is and would avoid the quoting issue entirely, no?
So unless I’m missing something,
- the cleanest fix might be to break up %normalize-system-command into two functions and
- the easiest fix might be to (instead) have it always return a list and concatenate that list in %redirected-system-command.
