bug#777: 23.0.60; emacs -batch does not exit w error if debug-on-error

If emacs is running in batch and an error occurs then it does not exit
with error status if debug-on-error is t. If debug-on-error is nil then
emacs exits with error status (which I think is correct).

To demonstrate this open the attached file and evaluate the comment
lines with compilation-start.

Thanks, I've implemented the change you suggested.

Without debug-on-error, Emacs exits with status -1, so that's what we'll
use.
