patch 9.0.2086: code cleanup for option callbacks needed Commit: https://github.com/vim/vim/commit/deba02ddd46e9e8adfe2f7800c6be19d8c8e1a4d Author: zeertzjq <zeertzjq@outlook.com> Date: Thu Nov 2 21:01:19 2023 +0100 patch 9.0.2086: code cleanup for option callbacks needed Problem: code cleanup for option callbacks needed Solution: remove flag os_doskip, it's not necessary, as we can check, whether an error message was returned Remove unnecessary field os_doskip Callback functions for boolean options set os_doskip immediately before returning an error message, so os_doskip isn't actually needed. closes: #13461 Signed-off-by: zeertzjq <zeertzjq@outlook.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
