-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 "/".
