        information.  We achieve this in one of these ways:

        * If no sudo is performed or the remote_user is sudo'ing to
          themselves, we don't have to change permissions.
        * If the remote_user sudo's to a privileged user (for instance, root),

        * If the remote_user sudo's to an unprivileged user then we attempt to
          grant the unprivileged user access via file system acls.
        * If granting file system acls fails we try to change the owner of the
          file with chown which only works in case the remote_user is
          privileged or the remote systems allows chown calls by unprivileged
          users (e.g. HP-UX)
        * If the above fails, we next try 'chmod +a' which is a macOS way of
          setting ACLs on files.
        * If the above fails, we check if ansible_common_remote_group is set.
          If it is, we attempt to chgrp the file to its value. This is useful
          if the remote_user has a group in common with the become_user. As the
          remote_user, we can chgrp the file to that group and allow the
          become_user to read it.
        * If (the chown fails AND ansible_common_remote_group is not set) OR
          (ansible_common_remote_group is set AND the chgrp (or following chmod)
          returned non-zero), we can set the file to be world readable so that
          the second unprivileged user can read the file.
          Since this could allow other users to get access to private
          information we only do this if ansible is configured with
          "allow_world_readable_tmpfiles" in the ansible.cfg. Also note that
          when ansible_common_remote_group is set this final fallback is very
          unlikely to ever be triggered, so long as chgrp was successful. But
          just because the chgrp was successful, does not mean Ansible can
          necessarily access the files (if, for example, the variable was set
          to a group that remote_user is in, and can chgrp to, but does not have
          in common with become_user).
