    Bug 608299 - Cut/copy error when selection has trailing comma
    
    When cutting or copying a selection that includes a trailing comma, the
    subsequent address was also getting copied to the clipboard.  The fix is
    to ignore trailing whitespace and commas when scanning the selection for
    email addresses.
