These all introduce or update existing Python Packaging Specifications,
and should follow the PyPA Specification processes. These are expected
to be Standards Track PEPs and are not informational.
This change also ensures that they get listed under the correct section
on the Packaging topic index.
Changes detected by Topy (https://github.com/intgr/topy), all changes
verified by hand, false positives have been omitted.
These range from straight-out misspellings to debatable hyphen placement.
The hyphen changes are supported by grammar manuals of style.
As pip now implements REQUESTED, the main reason to remove the file is gone,
so I'm adding it back as it is in PEP 376.
Possibly fixing the semantics is left to another PEP.
