the length check would not hurt - true. But it does not matter, in which
section (inet/inet6) the comments gets put. The reader method unifies
these comments anyway. So the comment *might* gets put in the inet6
section, event if there is another inet section. Should not matter,
should it?
Will add a "lenght" == 1 to the if.
