Comment # 4 on bug 1099755 from Matthias Gerstner

Thank you for the quick reaction. This issue seems to go deeper, however.
Actually openssh upstream removed support for tcpwrappers in favor of the
builtin Match syntax. See bug 1048982. On SLE-12-SP2 the feature was
reactivated but on SLE-15 it is not existing any more. Same for Factory.

So it looks like we should remove mentioning of ssh in hosts.* after all, and
maybe add a pointer to use the openssh Match keywords instead.
