Simply adding || exit $? (or not depending on whether - was in the command)
makes for a reasonably simple shell script. Basically take the current logic
and replace the set -e, set +e's with the exit's as needed.

Going with && between all commands (even newline separated and using sh -v)
will make setting up the script more complex in order to deal with these
sorts of things.

I think going with || exit $? and getting rid of -e is the best win here. 
Making the job code anymore complicated than it is...scary :-)
