patch 9.1.0284: make testclean is not able to delete failed screendumps Commit: https://github.com/vim/vim/commit/e20c7d7f442e0d42d78db7337c1b5e7a3ff91671 Author: Julio B <julio.bacel@gmail.com> Date: Tue Apr 9 21:22:41 2024 +0200 patch 9.1.0284: make testclean is not able to delete failed screendumps Problem: make testclean is not able to delete failed screendumps. Solution: Remove the "failed" directory when necessary. (Julio B) Patch 8.1.1080 changed the way that failed screendumps are saved, but the "rm -rf *.failed" clean command was not ported correctly. closes: #14468 Signed-off-by: Julio B <julio.bacel@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
