--- Comment #3 from James Z.M. Gao <gaozm55 at gmail.com> ---
thanks very much.

@dtucker another minor issue of the KnownHosts matching of `ssh-keygen
-F` is that 'host' and '[host]:22' are not equivalent.

ssh-keyscan host > k.txt # output: host key-type ...

ssh-keyscan -p 22 host # also output: host key-type ...

ssh-keygen -f k.txt -F host # found hostkey as expected

ssh-keygen -f k.txt -F '[host]:22' # found nothing, whereas we should
also match the same key as previous command
