Subject: [PATCH] (reassert_line_highlight, change_line_highlight): Functions
 removed. (initialize_w32_display): Don't set reassert_line_highlight_hook or
 change_line_highlight_hook. (hl_mode): Function removed.
 (reset_terminal_modes, set_terminal_modes, update_begin) (update_end,
 w32_face_attributes, initialize_w32_display): (clear_frame, ins_del_lines):
 Don't call it.
