This is a follow-up to GH-100811.
One of the changes in that PR isn't accurate in that
`os.path.join('', '')` will not end in a separator.
This reverts that change to the previous wording that used "only", but
explicitly calls out the case where the last part ends in a separator,
which is what caused confusin in GH-77607 and motivated the change
in GH-100811.

The example was showing the current version, but should be pinned to 3.7 to match the example command.

[3.11] gh-99952: [ctypes] fix refcount issues in from_param() result. (GH-100169)
Fixes a reference counting issue with `ctypes.Structure` when a `from_param()` method call is used and the structure size is larger than a C pointer `sizeof(void*)`.
This problem existed for a very long time, but became more apparent in 3.8+ by change likely due to garbage collection cleanup timing changes..

Python 2.x and up to 3.4 did not contain the "-32" in their registry name, so the 32 and 64-bit installs were treated equal. Since 3.5/PEP 514 this is no longer true, but we still want to detect the EOL versions correctly in case people are still using them.
Additionally, the code to replace a node with one with a lower sort key was buggy (wrong node chosen, replace never happened since parent was always NULL, replaced node never freed, etc)

We don't need direct C APIs to get at a bigint representation of PyLong but we
do want the few people who need to understand how.

When getaddrinfo returns an error, the output pointer is in an unknown state
Don't call freeaddrinfo on it. See the issue for discussion and details with
links to reasoning. _Most_ libc getaddrinfo implementations never modify the
output pointer unless they are returning success.

gh-101037: Fix potential memory underallocation for zeros of int subtypes (GH-101038)
This PR fixes object allocation in long_subtype_new to ensure that there's at least one digit in all cases, and makes sure that the value of that digit is copied over from the source long.
Needs backport to 3.11, but not any further: the change to require at least one digit was only introduced for Python 3.11.
Fixes GH-101037.

(cherry picked from commit 9a155138c5)
While the documentation for `optparse` mentioned that both `store_const` and
`append_const` store a constant value, it was not clear where this value was
coming from.
A link to `Option.const` makes this explicit.

The zipfile.Path open() and read_text() encoding parameter can be supplied as a positional argument without causing a TypeError again. 3.10.0b1 included a regression that made it keyword only.
Documentation update included as users writing code to be compatible with a wide range of versions will need to consider this for some time..
