ftp: verboselevel 1/2

[Ignatios Souvatzis <is%netbsd.org@localhost>]

Hi,

for domain names that resolve to multiple addresses, our ftp 
when verbose displays them when trying to connect to them.

When not verbose, it only ever displays the hostname if at all.

Sometimes, it is necessary to find out what exactly did work in
the recent past or sometimes, as much as what doesn't work now.

I have a patch lying around that adds peer address display to
the "connected" messages if (!verbose && interactive) (see below);
do we want that in-tree?

Regards,
	-is
