Improved (non-annoying) underlining

[Karl Kleinpaste <karl@charcoal.com>]

        _If you leave emphasization enabled then as you read this
        message you are seeing the annoying artifact that the empty
        whitespace at the beginning of lines is underlined when
        there is no good reason for it._

When the following patch is applied, Gnus will stop underlining (or
emphasizing, generally) whitespace.  I would appreciate it if some
kind write-enabled soul would commit this to CVS.
