patch 9.1.0205: Cannot use modifiers before :-Ntabmove Commit: https://github.com/vim/vim/commit/076faac5378cf517baa8c331c57488d39efadec0 Author: zeertzjq <zeertzjq@outlook.com> Date: Mon Mar 25 16:41:06 2024 +0100 patch 9.1.0205: Cannot use modifiers before :-Ntabmove Problem: Cannot use modifiers before :-Ntabmove. Solution: Check backwards from the command instead of checking from the start of the command line. Slightly adjust docs to make them more consistent (zeertzjq). closes: #14289 Signed-off-by: zeertzjq <zeertzjq@outlook.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
