hgweb: descend empty directories in web view

When a manifest has a series of directories with nothing in them but a single
directory, displaying the entire chain of empty directories allows for
navigation down to the first non-empty directory with a single click.

Because Java links package hierarchy to directory hierarchy, and because Java
conventions include at least three empty directories at the top of this
hierarchy, descending down empty directories is very common in Java web tools.
