	// Changes:  Sandeep V. Tamhankar (stamhankar@hotmail.com)
	//   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.
	//   1.0: Original
