FTP directory listings are now always retrieved in ASCII mode.
The FTP proxy properly escapes URI's and HTML in the generated
listing, and escapes the path components when talking to the FTP
server. It is now possible to browse the root directory by using
a url like:   ftp://user@host/%2f/ (ported from apache_1.3.24)
Also, the last path component may contain wildcard characters
'*' and '?', and if they do, a directory listing is created instead
of a file retrieval. Example: ftp://user@host/httpd/server/*.c
