I take it 6 because there are 2 per file - would it have been 2 + 4 + 6 = 12 prior to this fix?

Running CI, I'll merge if it comes back clean |

Looks like we're getting test failures on Python 3.7 + Windows.
I think the problem may be here - the other test in this module calls str on the Path before passing it to subprocess.run.
Summary
Using libCST cli tool allows to run a codemod over files inside a folder recursively. Context warning messages were not being cleaned between files, so warnings from one files could be passed to other files in the context. Because of that warnings were being shown wrongly in the summary and the total number of warnings was wrong as well.
Test Plan
python3 -m unittest libcst.codemod.tests.test_codemod_cli
