With newly built yaws-1.68 on OS X 10.4 and default yaws.conf, edited
only to listen on nonprivileged ports (8080 instead of 80, 8443
instead of 443), I get a 404 when pointing my browser at http://
localhost:8080 instead of the expected dir listing of /tmp. This is
with dir_listings either true or true_nozip.
The directory listing appears when I comment out "dav = true" in the
yaws.conf localhost container.
