Subject: Avoid warnings with grep 3.8
Patch-mainline: yes
Git-commit: f73f8d7f71de2878d3f92881a5fcb8eafd78cb5f
References: boo#1203230

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 "/".
