*** 1,5 ****
--- 1,36 ----
  2004-11-12  Kim F. Storm  <address@hidden>
  
+       * dispextern.h (struct glyph_row): New member extra_line_spacing.
+       (struct it): New member max_extra_line_spacing.
+       (MR_PARTIALLY_VISIBLE, MR_PARTIALLY_VISIBLE_AT_TOP)
+       (MR_PARTIALLY_VISIBLE_AT_BOTTOM): New helper macros.
+       (MATRIX_ROW_PARTIALLY_VISIBLE_P): Fix to return false if invisible
+       part of last line is only extra line spacing (so the text on the
+       line is fully visible). Use helper macros.
+       Add W arg (to use them).  All callers changed.
+       (MATRIX_ROW_PARTIALLY_VISIBLE_AT_TOP_P)
+       (MATRIX_ROW_PARTIALLY_VISIBLE_AT_BOTTOM_P): Use helper macros.
+ 
+       * window.c (window_scroll_pixel_based, Frecenter): Use
+       move_it_vertically_backward directly.
+       (Frecenter): Fix calculation of new start pos for negative arg.
+       Before, the new start pos was sometimes chosen too far back, so
+       the last line became only partially visible, and thus would be
+       either only semi-visible or automatically scrolled to the middle
+       of the window by redisplay.
+ 
+       * xdisp.c (init_iterator): Clear it.max_extra_line_spacing.
+       (move_it_vertically_backward): Don't recure to move further back.
+       (move_it_vertically): Remove superfluous condition.
+       (move_it_by_lines): Clear last_height when moved 0 lines.
+       (resize_mini_window): use it.max_extra_line_spacing.
+       (display_tool_bar_line): Clear row->extra_line_spacing.
+       (try_scrolling): Use move_it_vertically_backward directly.
+       (redisplay_window): Likewise.
+       (compute_line_metrics): Set row->extra_line_spacing.
+       (display_line, display_string): Likewise.
+       (x_produce_glyphs): Update it->max_extra_line_spacing.
+ 
        * xmenu.c (pop_down_menu): Return nil.
