From the set(1p) man page:
When this option is on, if a simple command fails for any of the
reasons listed in Consequences of Shell Errors or returns an exit
status value >0, and is not part of the compound list following a
while, until, or if keyword, and is not a part of an AND or OR list,
and is not a pipeline preceded by the ! reserved word, then the shell
shall immediately exit.
This allows us to remove all the "|| exit 1" statements we used to bail
out if one command fails.
