Add the 'bool' type and its values 'False' and 'True', as described in
...
PEP 285. Everything described in the PEP is here, and there is even
some documentation. I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison. I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.
Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.

Update docs for nested scopes.
...
Replace section 4.1 with section A.3.
The new section 4.1 is titled "Naming and binding." It includes the
text of section A.3 augmented with some of the detailed text from the
old section 4.1.
The \dfn, \index stuff is probably wrong, but I tried.
Also update other parts of appendix A to mention that nested scopes
and generators are standard features.

CO_FUTURE_DIVISION.

Clean up some markup cruft. A number of the macros that take no

parameters (like \UNIX) are commonly entered using an empty group to

last thing in the enclosing group. These cases were marked
inconsistently; the empty group is now *only* used when needed.
