patch 9.0.2125: File info disappears when 'cmdheight' has decreased Commit: https://github.com/vim/vim/commit/40ed6711bd385051021691980e8ce16375b4b510 Author: zeertzjq <zeertzjq@outlook.com> Date: Thu Nov 23 20:37:01 2023 +0100 patch 9.0.2125: File info disappears when 'cmdheight' has decreased Problem: File info disappears immediately when 'cmdheight' has just decreased due to switching tabpage and 'shortmess' doesn't contain 'o' or 'O'. Solution: Make sure msg_row isn't smaller than cmdline_row. fixes: #13560 closes: #13561 Signed-off-by: zeertzjq <zeertzjq@outlook.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
