patch 9.1.0206: unused display_text_first boolean var in win_line() Commit: https://github.com/vim/vim/commit/c8b47f26d8ae0db2d65a1cd34d7e34a2c7a6b462 Author: Dylan Thacker-Smith <dylan.ah.smith@gmail.com> Date: Tue Mar 26 18:05:01 2024 +0100 patch 9.1.0206: unused display_text_first boolean var in win_line() Problem: unused display_text_first boolean var in win_line() Solution: Remove unused display_text_first boolean variable (Dylan Thacker-Smith) The only place it is used, uses its initial constant value, then the following conditionally values set to the variable are unused. Specifically, it was commit 234c3fab28c14846b962c90097496b27ee1b4df8 that changed the use of display_text_first such that it doesn't have any effect. closes: #14305 Signed-off-by: Dylan Thacker-Smith <dylan.ah.smith@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
