fix for the bug reported

the corner case of '-HF' returns a string that is a hash for the whole
hostline and not just the host xor IP address which means that usually
it will return a hash for "HOST,IP". This will never be matched if
manually included into the known_host file since ssh hashes only one of
HOST or IP to look for a match in known_hosts file.

patch to fix this is included.
