[mm]: Regression-test Savannah #68052.
Add regression test for Savannah #68052. Nested marked lists (`ML`)
were using incorrect item marks after popping a nesting level with `LE`.
* contrib/mm/tests/marks-in-nested-ML-lists-are-correct.sh: Do it.
* contrib/mm/mm.am (mm_TESTS): Run test.
Test fails at this commit.
