What Bill has suggested won't do that, though; the two messages take
place in quite different places in an SSH login.  e.g., in the output
below, the "This is node Mussel" warning is what Bill was talking
about, and the "remote software version OpenSSH_3.8.1p1 Debian
1:3.8.1p1-8.brb3" is what you want to change.
