[issue27030] Remove deprecated re features

Ned Deily added the comment: It is unfortunate that the deprecation note did not explicitly mention replacement templates as well as regexp patterns. While there are good arguments to be made for either case, I think it makes more sense to treat the replacement template as following the

Serhiy Storchaka added the comment: Here is a patch that partially reverts changes of issue27030. It allows using unknown escapes in re.sub() replacement template, but they are deprecated and will be errors in 3.7. If this is good to you Barry, and Ned allows, it can be committed in 3.6 only.

R. David Murray added the comment: There is still the argument that we shouldn't break 2.7 compatibility unnecessarily until 2.7 is out of maintenance. That is: warnings are good, removals are bad. (I haven't read through this issue, so I may be off base.) -- nosy: +r.david.murray

Serhiy Storchaka added the comment: If you insist I could revert converting warnings to errors (only in replacement string or all?) in 3.6. But I think they should left errors in 3.7. The earlier we make undefined escapes the errors, the earlier we can define new special escape sequences
