      It is probably in Bram's todo list already, but he hasn't pushed the
      runtime files yet to the public repository (at
      http://code.google.com/p/vim/source/browse/#hg%2Fruntime)

      If he does and you have updated your runtime files, you'll find it
      somewhere in :h todo.txt (but don't expect a fix soon, the list is
      huge).

      regards,
      Christian

        This patch fixes it, but is probably wrong, since it makes screen
        redrawing much slower.
