The problem with a negative return value, at least as far as I can tell,
is that hush will print "exit not allowed from main input shell."
run_list_real() returns -2 if the called functions return is < -1, and
-2 means exit. If I'm misinterpreting something, let me know.  I don't
see any problem with using positive EINVAL, though, I didn't notice it
existed.
