Subject: bug#31222: automake 1.16.1 am__pep3147_tweak bug

The change to the "am__pep3147_tweak" variable included in <http://git.savannah.gnu.org/cgit/automake.git/commit/?id=006c4dfede96091f5bed622c17946cbec067347f> causes the generated Makefile files not to work on systems (such as macOS) where "sed" interprets "\n" in the substitution text as the letter "n" instead of as a newline.

For example, if I run "make distcheck" in the package created with the attached files, I see that in the uninstall phase it attempts to remove

  rm -f foo.*.pycnfoo.*.pyo

which results in the following error:

ERROR: files left after uninstall:
./lib/python3.6/site-packages/automake_python_test/__pycache__/foo.cpython-36.opt-1.pyc
./lib/python3.6/site-packages/automake_python_test/__pycache__/foo.cpython-36.pyc

A log file containing the output of running configure and make distcheck is attached.

Versions of OS and software:

macOS High Sierra 10.13.4
autoconf (GNU Autoconf) 2.69
automake (GNU automake) 1.16.1

Thanks,

-Mark
