I assume nothing just because the code for other protocols isn't using
ft_mode. However, for -incoming exec the parsing code as it is now
would trigger if the executed file ended with "ft_mode".
So now I think it should be at the beginning of the scheme for forward
compatibility with everything. Is it possible to detect a migration
scheme that does not support Kemari, and give an error in that case?
