> Let me reply that,  with the three critical instances of  wset_updated_mode_line just out-commented, when I scroll in a frame _with_ input focus, then the mode line is always correctly updated. If I scroll in a frame without input focus, then at least the percentage is always updated, and the line-number is update as soon as the (hollow) cursor reaches the top or the bottom of the range of text shown in the frame. In any case, with global-line-numbers-mode on, is there a situation where, in practice,  one needs to look at the line numbers as shown in the mode line?
