gopher and similar holes caused by writing to URL-specified ports

Given that gopher servers already exist on many random ports, it seems like
simply restricting ports isn't quite the right solution.

I realize this is somewhat up to the gopher guys, but how about declaring
that: any gopher URL that (a) specifies a port other than the "standard"
gopher port, and (b) includes a newline, is not valid?

Do gopher servers really (in practice) accept newlines in query strings?
