Paket.Pack uses outdated syntax

[Szer]

Usage of this command:
Paket.Pack(fun p -> { p with OutputPath = "bin" })
invokes this:
paket pack output "bin"

which produces this error:

Please use the new syntax: 'output' is the default argument and should be omitted.

Currently Paket pack command should be invoked like this:
paket pack "bin"

I think this is very trivial change in this line:

It would be nice to include this to version 4 also.
