+Subject: [PATCH] Make UtilsTests.test_filter_params Python 3.13+ compatible
+
+Since Python 3.13.0a1, docstrings are automatically dedented.
+See https://github.com/python/cpython/issues/81283
+and https://docs.python.org/3.13/whatsnew/3.13.html#other-language-changes
+
+As a result, using a docstring with leading space as a test case
+breaks the test assumption.
+
+The initial commit which introduced this test a decade ago
+(6c0c7914f3a57823834b1be492b307992f943629)
+does not specify why testing the spaces is important.
