User *can* specify a port number but it is just ignored.

In _user_at_host, _combination is called with style 'users-hosts', not
'users-hosts-ports'. For example,

% zstyle ':completion:*' users-hosts 'foo@xxxxxxxx:123'

% sshfs f<TAB><TAB>
% finger f<TAB><TAB>
% dsh -m f<TAB><TAB>

all of these complete to foo@xxxxxxxx and the 123 will never be offered.
So I wonder why : is in the pattern [:@]. Is it just to ignore the
port number (if it exists)?
