patch 9.1.0014: incorrect use of W_WINROW in edit.c
Problem: incorrect use of W_WINROW in edit.c
Solution: compare against curwin->w_height instead
Remove incorrect use of W_WINROW
In structs.h it is mentioned that w_wrow is relative to w_winrow, so
using W_WINROW doesn't make sense when comparing with window height.
This change won't lead to any observable behavior change:
The condition intends to check if there are 'scrolloff' lines between
the current cursor when the bottom of the window. When W_WINROW(curwin)
is added to curwin->w_height - 1 - get_scrolloff_value(), the condition
is instead satisfied when the cursor is on some screen line below that
position. However,
- If 'scrolloff' is smaller than half the window height, this condition
can only be satisfied when W_WINROW(curwin) == 0. And if it is not
satisfied, update_topline() does the actual scrolling.
- If 'scrolloff' is larger than half the window height, update_topline()
will put the cursor at the center of the window soon afterwards
anyway, because set_topline() now unsets VALID_TOPLINE flag starting
from
https://github.com/vim/vim-history/commit/7db7bb45b0f919ff0615d463ebd4fde881c69d1f.
To put it in another way,
https://github.com/vim/vim-history/commit/7db7bb45b0f919ff0615d463ebd4fde881c69d1f
makes the update_topline() just below correct the mistakes made in this
block, so this incorrect use of W_WINROW() no longer affects observable
behavior.
