Ah! Yes, I started working on a solution for this some time ago, that
instead would be automatic, by reading the executable and detecting
if it's an interpreted script, which would then check the arguments
and match the first one against that.

I think I have the interpreter detection done, just need to plug it
into the rest, but I'd have to look for the code, let me get 1.17.14
out of the way and I'll come back to you with more concrete plans or
code.

I'm afraid that would be a non-starter.
