From 43f5c0c4d0a608c04c3978adb45117f3943203b7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ricardo=20B=C3=A1nffy?= Date: Tue, 8 Oct 2019 17:41:00 +0100 Subject: [PATCH] [3.7] bpo-38294: Add list of no-longer-escaped chars to re.escape documentation. (GH-16442) (GH-16647) Prior to 3.7, re.escape escaped many characters that don't have special meaning in Python, but that use to require escaping in other tools and languages. This commit aims to make it clear which characters were, but are no longer escaped.
