On a broader note, why mention your present pay anyway in negotiating with a prospective employer?
Why not just say "on the basis of my experience, I believe a salary of X is in order". What you end up with is subject to negotiation but you shouldn't need to disclose your salary to support what you think you can legitimately claim. The employer is either willing to pay X or he isn't. What you currently earn should be irrelevant.
