There are lots of ways of doing things like this.  I wasn't suggested
that what I came up with was the best behaviour for anybody else, nor
that it's the only (or even best) way of implementing that behaviour.

That involves manually updating a list of hosts that I might want to SSH
to; mine and Bob's configurations automatically pick that up from
previous SSH activity.

That offers tab completion on the ssh command; mine and Bob's
configurations let you omit the 'ssh' and just type in the hostname.

In fact my implementation relies on you already having extended Bash
completion for the ssh command (since it uses its _known_hosts
function), but getting the list of hostnames from other files that are
lying around anyway.
