I'm reading the Bash Reference Manual, section 3.4.2
[https://gnu.org/s/bash/manual/html_node/Special-Parameters.html]:

    ($?) Expands to the exit status of the most
    recently executed foreground pipeline.
                      ^^^^^^^^^^^^^^^^^^^

I think this is a documentation bug because:

    $ ls nonexistent-file  # returned 2
    ls: cannot ...
    $ true &  # which is not a foreground pipeline
    $ echo $?
    0

Am I missing something?
