Actually, that particular result is because dirName gives you the parent directory, not because it's assuming that the end of the path is a file. Whether the end of the path is a directory or file or whatever is irrelevant (and to an extent has to be, because it doesn't check whether the path even exists, let alone what it points at). But really, the documentation should say that it gives the parent directory of the argument rather than the "directory part" of the argument.

Because this is such an easy fix, I submitted a PR to fix it.

I only changed "Returns the directory part of a path" to "Returns the parent directory of path." I did not add an example because I that might lead to discussion.
