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.

305ccbe27e bpo-30298: Weaken the condition of deprecation warnings for inline modifiers. (#1490) 
Now allowed several subsequential inline modifiers at the start of the
pattern (e.g. '(?i)(?s)...').  In verbose mode whitespaces and comments
now are allowed before and between inline modifiers (e.g.
'(?x) (?i) (?s)...').

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.

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.
