ssh tries to figure out the canonical names for
servers so that you don't get prompted over and
over as you use slightly different names for each
machine.

in /sys/src/cmd/ssh.c, after the call to setaliases,
put print("host aliases: %s\n", c->aliases);
perhaps one of those is matching a key in that file.

the message is accurate -- it's really that file
that has the key.
