    As I pointed out in
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/5285 (the
last time this issue came up), RFC1738 was updated by RFC1808 and
RFC2396 to include FTP URLs under the URI "umbrella".  This means that
although the second slash *is* required for absolute paths, it is *not*
required to be encoded as "%2F", it can just be a regular slash ("/").
So the second paragraph above should read "If you want a leading slash
on your chdir command, you need to insert a second slash (e.g.
'ftp://ftp.example.com//foo/bar/file.ext')."

    Hopefully the patched code allows this as well.
