Serhiy Storchaka c7ac7280c3 bpo-30375: Correct the stacklevel of regex compiling warnings. (#1595)
Warnings emitted when compile a regular expression now always point
to the line in the user code.  Previously they could point into inners
of the re module if emitted from inside of groups or conditionals.

Serhiy Storchaka 4ab6abfca4 bpo-30299: Display a bytecode when compile a regex in debug mode. (#1491)

Serhiy Storchaka 305ccbe27e bpo-30298: Weaken the condition of deprecation warnings for inline modifiers. (#1490)
Now allowed several subsequential inline modifiers at the start of the

now are allowed before and between inline modifiers (e.g.
'(?x) (?i) (?s)...').

Serhiy Storchaka 898ff03e1e bpo-30215: Make re.compile() locale agnostic. (#1361)
Compiled regular expression objects with the re.LOCALE flag no longer
depend on the locale at compile time.  Only the locale at matching
time affects the result of matching.

Nick Coghlan ace5c0fdd9 bpo-29571: Use correct locale encoding in test_re (#149)
``local.getlocale(locale.LC_CTYPE)`` and
``locale.getpreferredencoding(False)`` may give different answers
in some cases (such as the ``en_IN`` locale).

``re.LOCALE`` uses the latter, so update the test case to match.

Victor Stinner b44fb128ae Implement rich comparison for _sre.SRE_Pattern
Issue #28727: Regular expression patterns, _sre.SRE_Pattern objects created by
re.compile(), become comparable (only x==y and x!=y operators). This change
should fix the issue #18383: don't duplicate warning filters when the warnings
module is reloaded (thing usually only done in unit tests).

Serhiy Storchaka 662cef66d7 Issue #25953: re.sub() now raises an error for invalid numerical group
reference in replacement template even if the pattern is not found in
the string.  Error message for invalid group reference now includes the
group index and the position of the reference.
Based on patch by SilentGhost.
