patch 9.1.0163: Calling STRLEN() to compute ml_line_textlen when not needed Commit: https://github.com/vim/vim/commit/82e079df814f7372e9579450730062b205449efa Author: zeertzjq <zeertzjq@outlook.com> Date: Sun Mar 10 08:55:42 2024 +0100 patch 9.1.0163: Calling STRLEN() to compute ml_line_textlen when not needed Problem: Calling STRLEN() to compute ml_line_textlen when not needed. Solution: Use 0 when STRLEN() will be required and call STRLEN() later. (zeertzjq) closes: #14155 Signed-off-by: zeertzjq <zeertzjq@outlook.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
