        * src/rm.c (long_opts): Change the name of each undocumented, for-
        testing-only option to start with `-', so that it cannot render
        ambiguous any prefix it happens to share with some other option name.
        Problem reported by Eric Blake.
        * src/head.c (long_options): Likewise.
        * src/tail.c (long_options): Likewise.

        * tests/misc/head-elide-tail: Update uses of undocumented, for-
        testing-only --presume* options to start with `---'.
        * tests/rm/dangling-symlink: Likewise.
        * tests/rm/dir-no-w: Likewise.
