Close. There are a few conditions under which set -e has no effect. The
&& and || operators are a two places, but there are more.

Don't rely on set -e if its behavior is not what you want. Check exit
statuses yourself and stop execution when appropriate. You could use
set -e and check exit statuses in the exception cases to reduce the
amount of extra work.
