[PATCH 8/9] www: extra redirects for the '/'-challenged

[Eric Wong <e@80x24.org>]

Omitting a slash should not be fatal if unambiguous.  Add
fallbacks so users who expect a directory structure-like
experience can have it at the cost of one extra HTTP
request/response pair.

This matches behavior of static sites.
