(formatter.py):  Establish a consistent space-handling policy, so that all
        spaces are handled by the outermost context in which they might be
        considered.  (I.e., softspaces at element boundaries migrate
        outwards.)

        For instance: "<A> <IMG> </A>" becomes " <A><IMG></A> ".

        This avoids some of those nasty underlined spaces around images.  It
        does not affect spaces *between* images within an anchor.

(formatter.py):  Added required parameter to the NullFormatter class; this
        was omitted by accident.

        Made AbstractFormatter.add_literal_data() handle preceeding softspace
        correctly instead of expecting the caller to do it.

(formatter.py):  Correct assert_line_data() to update all internal conditions;
        This now handles headers with only image content immediately followed
        by anything.
