+set -e

Is this really necessary? I really like to avoid `set -e`, in
particular when we do pretty much everything in && chains anyway.

Agreed, not really necessary here as we just invoke one command.  Out of
curiosity: Why do you try to avoid it? I set it by default in all my
scripts.

I try to avoid it because it encourages a style that omits helpful error
messages.

Yeah, we prefer to define and use a die() function like this:

die () {
    printf >&2 '%s\n' "$*"
    exit 1
}

do_something || die "meaningful error message"
