It happens to contain a shell-script (depcomp) near the end of the
tarfile, and that shell-script happens to have a footer that starts
fewer than 3000 characters from the end of the tarfile, and happens to
contain:

    # Local Variables:
    # mode: shell-script
    # sh-indentation: 2
    # eval: (add-hook 'write-file-hooks 'time-stamp)
    # time-stamp-start: "scriptversion="
    # time-stamp-format: "%:y-%02m-%02d.%02H"
    # time-stamp-time-zone: "UTC"
    # time-stamp-end: "; # UTC"
    # End:

(The mode setting is superfluous since it begins with #!/bin/sh anyway.)

So hack-local-variables decides the tarfile should be in sh-mode.
