I am encountering a small bug when using ssh-keygen -l with
known_hosts files. For lines that have comments, the hostname is not
diplayed in the ssh-keygen -l output:
servo:/tmp/cdtemp.mgJxDc 0$ cat known_hosts.nocomment

As you can see in the last command, the hostname is not present in the
display, although the comment is.
The monkeysphere program uses the comment field in known_hosts files,
so this may present a problem for users of that program.
Thanks for the help.
