From 88bce0e24c8f777fce1f726b4553bd32286bba04 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Thu, 11 Feb 2021 02:08:05 +0000 Subject: ref-filter: hoist signature parsing When we parse a signature in the ref-filter code, we continually increment the buffer pointer. Hoist the signature parsing above the blank line delimiting headers and body so we can find the signature when using a header to sign the buffer.
