Allow directories in EXTRA_PATH_METADATA

Browse source 
Metadata applied to a directory will apply to all files under
it. In case of conflicts, child paths beat parent paths, so metadata
applied to `dir/subdir/file.md` will take precedence over that applied
to `dir/subdir`, which will take precedence over just `dir`.
