I wanted to point you to the shown directories.

In case you didn't name your directories like the developer before you,
you change into the source dir and strip the leading parts of the path
contained in the patch. So if you're passing -p1 it strips the first
part and patches CONFORMANCES in the current directory. N just keeps you
from adding same patch again.
Patch doesn't care much about how the diff was created. It cares about
the patch being unified and the path of the files to patch.
Perhaps I should better think for my own before posting... 8-)
