patch 9.1.0093: Still a qsort() comparison function that returns result of subtraction Commit: https://github.com/vim/vim/commit/77078276bfe695070441a1bbdc02949d31de8922 Author: zeertzjq <zeertzjq@outlook.com> Date: Sat Feb 10 13:24:03 2024 +0100 patch 9.1.0093: Still a qsort() comparison function that returns result of subtraction Problem: Still a qsort() comparison function fuzzy_match_item_compare() that returns result of subtraction (after 9.1.0089). Solution: Use an explicit comparison instead of subtraction. (zeertzjq) closes: #14004 Signed-off-by: zeertzjq <zeertzjq@outlook.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
