It completes some command instead of a host.

Using sh -c 'env HOME=$(mktemp -d) fish' has the same behaviour.

Yeah, the ssh completion needs to know about the actual option arguments.

In general this is a hard problem - in fact it's impossible without knowing the actual options.

In particular it means that the ssh completions need to be altered to use argparse.

This used to work in 2.something. Do I remember incorrectly?
