patch 9.1.0022: Coverity complains about improper use of negative value Commit: https://github.com/vim/vim/commit/49471963fefbdf78239d9066d84e14e1876fb177 Author: Christian Brabandt <cb@256bit.org> Date: Fri Jan 12 17:48:08 2024 +0100 patch 9.1.0022: Coverity complains about improper use of negative value Problem: Coverity complains about improper use of negative value Solution: Add a condition to validate that keytyped is larger or equal to 0 Apparently patch 9.1.0006 made it more explicit for Coverity, that the TOLOWER_LOC() macros do not handle negative values properly. However, that condition has always been there even before that, so add a condition to verify that keytyped is indeed at least 0 closes: #13824 Signed-off-by: Christian Brabandt <cb@256bit.org>
