Patch to improve -p error message.

[Mo DeJong]

Hi all.

I got sick of getting a lame error message when I typed
the wrong thing in for a -p argument, so I wrote
up this patch.

Bad:

% ssh -p L4501 localhost
Secure connection to localhost refused.

Good:

./ssh -p L4501 localhost
Bad port specification 'L4501'.
