+Subject: [PATCH] Allow both pre- and post- PEP 610 outputs in
+ test_venv_special_chars_issue252
+
+pip 20.1+ supports PEP 610 https://www.python.org/dev/peps/pep-0610/
+Hence the output is changed a bit.
+This was acknowledged in 553d6f282119481cbd4cf2a78e633eb8b506659e.
+
+Here we allow to run the tests with pip 19.3.x again
+by relaxing the regex to match both the old and the new format.
