I decided to leave the (slightly expanded) Other Improvements
entry as well, since someone looking for command line behavior
changes isn't going to look in the 'sys' module section.

This fifth tuple element is unsupported in an old hg version still used on
one buildbot, and it is not really necessary (only used in touch --help).

Also updated the base64 module title and introduction to adjust for
the fact that these new encodings are included.

Also adjusted the wording about the base64 alphabets (see
issue #20837).

Also clarify the documentation of this feature.

Several of the introspection changes in Python 3.4 are indirect,
where inspect module changes affected pydoc, and those in turn
affected the help builtin. This update adds versionchanged
notes in the key locations, as well as more coverage in the
What's New document (in particular, a note in the porting
section regarding the expanded domain for inspect.getfullargspec).

Added versionchanged to docs.

Also updated the docs and added the aliases mentioned by the
references.

Since 3.3.4.... :(

This was perhaps on the border between a bug fix and a feature since
the Python3 docs did not originally say it was unix only.  However, the
functions never worked anywhere but unix, and the docs were changed to
say it was unix only well before the windows support was added.

Unfortunately, windows support was added in 3.3.4 as well as 3.4.
That leaves us in the uncomfortable position of needing the tag to say
"version changed: 3.3.4" :(

Thanks to Nick Coghlan for the suggestion.

pylauncher.vcxproj already has the same dependency, and adding it to
the pywlauncher project eliminates the possibility of the pywlauncher
build failing when building the solution in parallel.  In particular,
pywlauncher may fail to build when doing a "Rebuild Solution" from the
VS Build menu.

Merge with 3.3.

Also tweaked the docs a bit and added the missing entry for
the ipv6 is_global.

as documented.  The pattern and source keyword parameters are left as
deprecated aliases.
