zfanon and nslookup

[Tanaka Akira <akr@m17n.org>]

I found that the function nslookup may causes trouble with zfanon.

Z:akr@coulee% Src/zsh -f
coulee% autoload -U nslookup zfinit
coulee% zfinit
coulee% zfanon ftp.zsh.org

Hm.  This prompt is for nslookup.

coulee% set -x
coulee% zfanon ftp.zsh.org

So, the function nslookup shouldn't work interactively if a query is
specified on a command line.
