Add an option to specify the number of overlapping lines when scrolling page by page (0 by default because this is ELinks' current behaviour). I think that repeating the last line of the screen when scrolling makes reading long pages easier; this also is what slrn does, so with this patch I can make them behave in the same way when scrolling page by page.
