This commit resolves all outstanding duplicate label
and duplicate citation warnings.
I have not yet addressed unreferenced footnote warnings.
I took the general strategy of replacing a target above a section heading
with references directly to that section heading,
or where impractical, disambiguting the target with ``PEP NNN``.
I also converted all the citations in PEP 482 to links,
as they were causing duplicate citation warnings.
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.
