convert existing .ssh/config file to .ssh/config.advanced

this was never added, was it?

[moul]

It wasn’t

It can be done quite easily with hacks,
but the best way to do it is to redesign a little bit the ˋconfig` package to make it able to Marshall/Unmarshall both file formats (this should be helpful for other issues)

That’s something I can try to do if nobody else do it before
