Hi,

The attached example.zip contains an example where the patch type detection fails to detect a git patch because the filename contains a dash. See README.txt in the example directory for more details.

Note that I added three diagnostic lines of code to the path.py module in the example directory.

I suggest that the regular expression r'diff --git a/[\w/.]+ b/[\w/.]+' should be extended accordingly.

P.S: Thanks for sharing your code!
