I think it would make sense to have 2 domains in the list just to make sure that
each domain is treated separately by the recoding process. The reason for this
is that if we take something like 'xn--domain1\nxn--domain2\n' and then recode
it without breaking into separate lines, the result is different from breaking
it into separate lines and then processing each line separately (this is what we
want).

The checking in line 77 will need to be a bit more sophisticated to check that
the result is really what we want.

Done.
