+Subject: [PATCH] clean up properly after test_git
+
+Restore original directory after test_git.  Otherwise, next tests
+are run in non-existing directory and fail:
+
+[...]
+>           cwd = os.getcwd()
+E           FileNotFoundError: [Errno 2] No such file or directory
+
+/usr/lib/python3.9/site-packages/gunicorn/util.py:443: FileNotFoundError
+
+While at it, reflow the logic so that the temporary directory is always
+cleaned, even if the test fails in middle of setup.
