patch 9.1.0374: wrong botline in BufEnter Commit: https://github.com/vim/vim/commit/eb80b8304efb6dfeaa8d01dd41fe281df4894240 Author: Jaehwang Jung <tomtomjhj@gmail.com> Date: Fri Apr 26 18:48:48 2024 +0200 patch 9.1.0374: wrong botline in BufEnter Problem: When :edit an existing buffer, line('w$') may return a wrong result. Solution: Reset w_valid in curwin_init() (Jaehwang Jung) `do_ecmd()` reinitializes the current window (`curwin_init()`) whose `w_valid` field may have `VALID_BOTLINE` set. Resetting `w_botline` without marking it as invalid makes subsequent `validate_botline()` calls a no-op, thus resulting in wrong `line('w$')` value. closes: #14642 Signed-off-by: Jaehwang Jung <tomtomjhj@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
