Thanks for you help and suggestions.

I have just installed changes that allows fringe bitmaps to be up to
16 bits wide, and properly support any width between 1 and 16 on X.

I believe I have made the necessary changes to the W32 and MAC ports
(including not doing bit-swapping on MAC_OS).  As we previously
discussed, the code is simpler on both W32 and MAC after these change,
but as usual I cannot test whether it works.


Vi fans may want to try this...

(require 'fringe)

(define-fringe-bitmap  
 [#b000000000
  #b000100100
  #b001010100
  #b001001000]
 nil 9 'top empty-line-fringe-bitmap)

(setq indicate-empty-lines t)
