Currently, PuTTY's choice of SSH protocol can only be expressed as a preference. If you ask for an SSH-2 connection and only SSH-1 is available, or vice versa, PuTTY will fall back to whatever it can use. For security reasons we should also allow the user to specify "SSH-2 or nothing", so that if PuTTY couldn't make an SSH-2 connection it would give up rather than fall back to SSH-1. For symmetry, we should also support "SSH-1 or nothing", though that seems less obviously useful.
Audit trail for this wish.
