patch 9.1.0642: Check that mapping rhs starts with lhs fails if not simplified Commit: https://github.com/vim/vim/commit/9d997addc7bd0fd132a809cf497ed816e61fcd25 Author: zeertzjq <zeertzjq@outlook.com> Date: Mon Jul 29 21:10:07 2024 +0200 patch 9.1.0642: Check that mapping rhs starts with lhs fails if not simplified Problem: Check that mapping rhs starts with lhs doesn't work if lhs is not simplified. Solution: Keep track of the mapblock containing the alternative lhs and also compare with it (zeertzjq). fixes: #15376 closes: #15384 Signed-off-by: zeertzjq <zeertzjq@outlook.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
