+From f73f8d7f71de2878d3f92881a5fcb8eafd78cb5f Mon Sep 17 00:00:00 2001
+From: Jean Delvare <jdelvare@suse.de>
+Date: Fri, 9 Sep 2022 10:10:37 +0200
+Subject: Avoid warnings with grep 3.8
+
+GNU grep version 3.8 became more strict about needless quoting in
+patterns. We have one occurrence of that in quilt, where "/"
+characters are being quoted by default. There are cases where they
+indeed need to be quoted (typically when used in a sed s/// command)
+but most of the time they do not, and this results in the following
+warning:
+
+grep: warning: stray \ before /
+
+So rename quote_bre() to quote_sed_re(), and introduce
+quote_grep_re() which does not quote "/".
+
