/* 1.1.2: Fixed a bug where trailing . in e-mail address was passing

            (the bug is actually in the weak regexp engine of the browser; I

            simplified the regexps to make it work).

   1.1.1: Removed restriction that countries must be preceded by a domain,

            so abc@host.uk is now legal.  However, there's still the 

            restriction that an address must end in a two or three letter

            word.

     1.1: Rewrote most of the function to conform more closely to RFC 822.
