Of course, when I go to amend the commit, the commit message says

	We will expand the path_matches_dir_pattern() method in a following
	change.

which means that more will follow that will actually care about the
pattern and matching as a directory.

After looking at the extension in the next patch, do you still think a
rename is necessary? Specifically, this diff hunk:
