Well, yes. The syntax of the /etc/hosts file is first an IP and then
a hostname. Somebody will possibly correct me, but I don't recall
any valid use of /etc/hosts that has lines of host names without IPs.

} I would like to keep the completion from ~/.ssh/config and add
} completion from /etc/hosts.
This shouldn't change the behavior with respect to ~/.ssh/config
because that's read in _ssh_hosts rather than in _hosts where the
style above applies.
_hosts reads ~/.ssh/known_hosts whether or not the program named by
the command style returns anything.
However, ~/.ssh/config will be skipped if the users-hosts tag finds
any matching hosts, which is likely to happen if you are starting
from a blank word, because users-hosts calls _hosts which will look
in known_hosts. If you start with a prefix on the line that matches
a host in ~/.ssh/config and does NOT match one in ~/.ssh/known_hosts,
you should get a completion.

}
} can I simply copy Unix/_ssh from zsh 5.0. and use it on zsh 4.3.17 ?
I don't think so (you'd need at least _hosts as well) but in any case
it wouldn't change anything because even 5.0+ is not expecting you to
have just dumped a bunch of bare host names into /etc/hosts like that.
