[vim/vim] "zb" scrolls incorrectly with cursor just above fold (PR #20923)
zeertzjq
Problem: "zb" scrolls incorrectly with cursor just above fold.
Solution: Handle boff.lnum being set to the last line of a fold.
With the cursor just above fold, botline_forw() moves boff.lnum to the
last line of the fold, but curwin->w_botline is at the first line of the
fold, so the boff.lnum == curwin->w_botline condition never holds.
Instead, check that boff.lnum has just moved to or past w_botline by
comparing its previous value with w_botline.
Also make a similar change to the loff.lnum check above for symmetry.
That one doesn't change behavior, as topline_back() sets loff.lnum to
the first line of a fold.
