Done, and also implemented Paul's suggestion.

        test-framework-sh: Avoid /bin/sh on AIX 7.2 due to its printf built-in.
        Reported by Paul Eggert in
        <https://lists.gnu.org/archive/html/grep-devel/2019-12/msg00020.html>.
        Simplification by Jim Meyering.
        * tests/init.sh (gl_shell_test_script_): Add a test of printf of an
        octal escape sequence in a UTF-8 locale.
