patch 9.0.1800: Cursor position still wrong with 'showbreak' and virtual text Commit: https://github.com/vim/vim/commit/6a3897232aecd3e8b9e8b23955e55c1993e5baec Author: zeertzjq <zeertzjq@outlook.com> Date: Sun Aug 27 19:04:14 2023 +0200 patch 9.0.1800: Cursor position still wrong with 'showbreak' and virtual text Problem: Cursor position still wrong with 'showbreak' and virtual text after last character or 'listchars' "eol". Solution: Remove unnecessary w_wcol adjustment in curs_columns(). Also fix first char of virtual text not shown at the start of a screen line. closes: #12478 closes: #12532 closes: #12904 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: zeertzjq <zeertzjq@outlook.com>
