A pattern I typically do

    foo && \
    bar && \
    baz && \
    :

or so, which is less verbose but short and sweet. Obviously slightly different, but : (no-op) seems applicable to your situation.

You don't need the backslashes in that case. As with lines ending in pipes and a few other places, the line continuation is implicit after the &&:

Huh, neat. So I picked that habit up from writing Dockerfiles, which does let you do
RUN foo && \ bar && \ :
but not
RUN foo && bar && :
(I just tested it), but more recently you can just write
RUN <<EOF foo bar EOF
so with the caveat of needing to `set -e` the whole thing might be a moot point now:)

Clever! ...almost TOO clever... ;-)

That's a great technique, but the `:` as no-op is tough to expect bash-normies to understand (and a tough "operator" to search for). Thanks for sharing, it'll definitely stay in my back pocket!
