From 7aabeee93edb2e7ab03954e235683bfd9d8f29eb Mon Sep 17 00:00:00 2001 From: Andrew Jones Date: Thu, 10 Aug 2023 14:15:28 +0200 Subject: [PATCH] Makefile: Fix grep warning grep (at least my version, grep-3.8-3.fc38.x86_64) warns with "grep: warning: stray \ before -". Fix the warning by making the command line input to grep less ambiguous.
