New host breaks ssh

[pikeas]

I'm running a one-liner to update a file across a group of servers:

$ for i in {1..10}; do scp file server$i.domain.com:/etc; done
file                                                                                                          100% 2168    11.1KB/s   00:00
file                                                                                                          100% 2168    11.1KB/s   00:00
...

Are you sure you want to continue connecting (yes/no)? yes

WARN[0000] '~/.ssh/config' has been rewritten.  SSH needs to be restarted.  See https://github.com/moul/advanced-ssh-config/issues/122 for more information.
/Users/apikeas/.ssh/config: line 62: Bad configuration option: ver8.domain.com,
/Users/apikeas/.ssh/config: terminating, 1 bad configuration options

This is reproducible - the first unknown host connects successfully, the next unknown host causes the above failure. The error on line 62 is always a truncated host name.

Fixed :)
