--------------------------+-----------------------------
 WordPress valids that the domain portion of the email address (after the
 @) doesn't have leading or trailing periods, or more than one period
 consecutively, but the same check isn't done on the portion before the @.
 This means that the following email addresses validate:

 .name at email.com
 name. at email.com
 first..last at email.com

 The attached patch will resolve this, although it might need a little
 refactoring to deal with the duplication in trimming periods and
 whitespace.
