Subject: www: extra redirects for the '/'-challenged
X-Git-Tag: v1.0.0~909
X-Git-Url: http://www.git.stargrave.org/?a=commitdiff_plain;h=6e509b610078e6758b98d1151ea775f76fd22cbe;p=public-inbox.git

www: extra redirects for the '/'-challenged

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.
