patch 9.0.2022: getmousepos() returns wrong index for TAB char Commit: https://github.com/vim/vim/commit/b583eda7031b1f6a3469a2537d0c10ca5fa5568e Author: zeertzjq <zeertzjq@outlook.com> Date: Sat Oct 14 11:32:28 2023 +0200 patch 9.0.2022: getmousepos() returns wrong index for TAB char Problem: When clicking in the middle of a TAB, getmousepos() returns the column of the next char instead of the TAB. Solution: Break out of the loop when the vcol to find is inside current char. Fix invalid memory access when calling virtcol2col() on an empty line. closes: #13321 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: zeertzjq <zeertzjq@outlook.com>
