It's tempting, but I think not. In principle, the caller can
pass any value as the first arg of spawn: it'll simply end up
as sys.argv[0] in Python terms. If spawnl were the way of the
future, I'd be inclined to argue for the change. As it it, though,
I'd simply apply the patch and, possibly, add a line to the docs
indicating that the args must be non-empty.

(I started to import the patch yesterday but something got in the
way; I'll see if I can get it done today).
