When Christian implemented /about/image.jpg handling, it brought up
the issue of /about vs /about/ and I wound up adding this commit 
to canonicalize that url so that rendered content would always wind up
referencing the correct relative path.
We have another potential issue, however. git.zx2c4.com/cgit and
git.zx2c4.com/cgit/ have the same content, yet different URLs. This
might be looked upon unfavorably by search engines. One rectification
is to add a meta tag. Another, and one I'd like to consider here, is
to always add the trailing slash to pages with the same 301 trick as
I'm interested in hearing some thought and considerations (and even
diffs if someone beats me to it?) before I merge this though.
