Subject: [PATCH] add a missing "/" to autoindex paths

With the following directory structure:

/srv/gmni:
baz/  foo/

/srv/gmni/baz:
a

/srv/gmni/foo:
bar/

/srv/gmni/foo/bar:
b

trying to access gemini://somesite/ with autoindex=on works,
but accessing /foo fails because it tries to stat /srv/gmni/foobar
instead of /srv/gmni/foo/bar. This commit fixes that by adding a trailing slash.
