Are you talking about d6b8fc3 (gitignore(5): Allow "foo/" in ignore list
to match directory "foo", 2008-01-31), specifically this part of the
manual?

- If the pattern does not contain a slash '/', git treats it as

pathname without leading directories.
Incidentally I notice that the above patch did not include new tests to
see if "git clean" honors the corrected pattern matching rule. If your
"real problem" is too complex to describe, perhaps an additional test that
exercises "git clean" with test_expect_failure would help motivated
parties to triage and fix the problem.
"git clean" has always been an ugly and unreliable stepchild, and I would
not be surprised at all if it is ridden with corner case bugs, especially
around the area to skip untracked directories; but in this case you are
not dealing with a directory but a symlink, and it should not get confused
by the fact that the symlink happens to point at a directory.
