This text is hard to understand because of multiple negations (don't,
unless, no fringe).  I suggest to change it into something like this:

  If nil and the left fringe is displayed, don't scroll the
  compilation output window; the arrow in the left fringe indicates
  the current message.  If nil and there's no left fringe, always
  scroll and display the current message at the top of the compilation
  window.

Also, please use two spaces after the period that ends a sentence.

Thanks.
