I worry slightly that wording like this might paint ourselves into a
similar corner of only correctly handling files as paths, rather than
also handling directories as paths, and/or which presumes the
no-overlay mode that I find problematic.  Maybe your "at times" just
meant "when dealing with a path that is a file that existed in the
given source", but I wonder if you are pushing more than that?
