+Subject: [PATCH] input: Fix compiling against libedit with -fno-common
+To: dash@vger.kernel.org
+
+With -fno-common, which will be enabled by default in GCC 10, we see
+this error:
+
+ld: input.o:(.bss+0x0): multiple definition of `el';
+histedit.o:(.bss+0x8): first defined here
+
+To fix this, simply remove the definition as it is not needed.
