Mathew,
thank you for packaging ssh related stuff. It is very important for
security. I regularly use ssh as well as scp. It would be great if the
two packages were more flag-compatible. For example, when specifiying
the port on the command line ssh takes -p and scp -P. -p for scp is
preservation mode. May I suggest to switch the meaning of -p and -P for
scp? I am not sure if this can be done because of path-depency problems
(ppl rely on the old behaviour). I also assume this is something that
should be fixed upstream? Thank you for considering my little
suggestion.
Best regards
Rolf Leggewie

scp(1) says:
-P port
Specifies the port to connect to on the remote host.
Note that this option is written with a capital 'P',
because -p is already reserved for preserving the times
and modes of the file in rcp(1).
I'm afraid that it isn't possible to change this, because the way scp
works means that when you run 'scp -p' on a client it makes an ssh
connection to a server and runs 'scp -p' (with some other options) on
the server. If the command-line options were changed, it would break
compatibility with existing scp clients.
sftp is more sensibly designed and does not suffer from command-line
option compatibility problems like this.
See http://www.openssh.org/faq.html#2.10 for upstream's response to a
similar question. Although that's about adding new features or options,
it's clear that changing existing features or options is even more
likely to break compatibility.
Cheers,
