Oooh I'm going to make your day then... I used -p / -P for a long while
without complaint.  Then I discovered one can set up a two line stanza
per server in the client side ~/.ssh/config:

Host some.server.com
Port 12345

will magically get ssh and scp to "know" the correct default port for
any ssh activity to some.server.com.  COOL!  That and ssh-agent holding
passphrases: safe ssh on a random listening port is really transparent
and easy.
