A couple of minor problems. I wouldn't rock the code too much as we can
live with them. I am prepared to accept the patch as it is.

If autoresume reaches the last module in the autoresume file, it will
get built anyway, whether it has previously passed or failed.

--autoresume takes precedence over -o. They don't really make sense
together, so whichever one takes precedence is a luck of the draw and is
confusing.
