Here is an easy way to figure out how and/or-lists work: Given that &&
and || have the lowest precedence of all operators (except for ; and &),
they can be thought of as concatenating commands/blocks/pipelines, and
the execution rule for an and/or-list is:

If the exit-status of the command/block/pipeline is 0, continue after
the next &&, otherwise continue after the next || in the and/or-list.
