The problem is that all the option handling in _ssh was done ages
ago and it has moved on a bit since then. The patch below brings
it up to date with recent OpenSSH and includes completion for sftp.
Also, I don't know why it was completing ssh options after scp -o.
It seems to me that it only allows options from the config file
there. Note that much of the patch is reindentation.
