patch 9.1.0140: cursor on wrong row after 1 char 'below' virtual text when EOL is shown Commit: https://github.com/vim/vim/commit/da0c9137d1ec96f4d79b818502d2f921a21f710e Author: Dylan Thacker-Smith <dylan.ah.smith@gmail.com> Date: Tue Feb 27 20:25:10 2024 +0100 patch 9.1.0140: cursor on wrong row after 1 char 'below' virtual text when EOL is shown Problem: The cursor screen row was incorrectly being calculated when the cursor follows a 1 character text_align 'below' virtual text line, resulting in the cursor being shown on the wrong line. This was caused by a cell size of 2 instead of 1 being used for the EOL character, which propagated to the calculation of space for putting the 'below' virtual text on its own line. (rickhowe) Solution: Fix the size used for the EOL character in calculating the cursor's screen position (Dylan Thacker-Smith) fixes: #11959 related: #12028 closes: #14096 Signed-off-by: Dylan Thacker-Smith <dylan.ah.smith@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
