gh-141226: Deprecate PEP-456 support for embedders ( #141287 )
...
Deprecate PEP-456 [1] support for providing an external definition
of the string hashing scheme. Removal is scheduled for Python 3.19.
Previously, embedders could define the ``Py_HASH_ALGORITHM`` macro to be
``Py_HASH_EXTERNAL`` [2] to indicate that the hashing scheme was provided
externally but this feature was undocumented, untested and most likely
unused.

raised a SystemError instead of a TypeError, and allow to explicitly use `None`
for `scheduler` and `setpgroup` as specified in the docs.

gh-144694: Fix re.Match.group() doc claiming [1..99] range limit ( #144696 )
...
The documentation incorrectly stated that numeric group arguments
must be in the range [1..99]. This limit was removed in Python 3.5
(bpo-22437). Replace with "a positive integer" since the next
sentence already documents the IndexError for out-of-range values.

gh-144156: Fix email header folding concatenating encoded words ( #144692 )
...
The fix for gh-92081 (gh-92281) was unfortunately flawed, and broke whitespace handling for encoded word patterns that had previously been working correctly but had no corresponding tests, unfortunately in a way that made the resulting headers not RFC compliant, in such a way that Yahoo started rejecting the resulting emails. This fix was released in 3.14 alpha 1, 3.13 beta 2 and 3.12.5. This PR fixes the original problem in a way that does not break anything, and in fact fixes a small pre-existing bug (a spurious whitespace after the ':' of the header label if the header value is immediately wrapped on to the next line).
