instead of faking it by hand.  It *is* a var object, and nothing but
hysterical raisins to pretend it's an oddball.

copy the sign too.  Added a test to test_descr to ensure that it does.

to fix was almost certainly a bug in _PyLong_Copy (which I'll fix next).

section use this class instead of UnixMailbox as per the comments in
the latter's class.

Bug fix candidate for 2.2.1.

Due to the bizarre definition of _PyLong_Copy(), creating an instance
of a subclass of long with a negative value could cause core dumps
later on.  Unfortunately it looks like the behavior of _PyLong_Copy()
is quite intentional, so the fix is more work than feels comfortable.

This fix is almost, but not quite, the code that Naofumi Honda added;
in addition, I added a test case.

Support GMP version >= 2.

Bug fix candidate for 2.1 & 2.2.

rexec.

When using a restricted environment, imports of copy will fail with an
AttributeError when trying to access types.CodeType.

Bugfix candidate (all the way back to 1.5.3, but at least 2.1.3 and
2.2.1).

A file-static "threads" dict mapped thread IDs to Windows handles, but
was never referenced, and entries never got removed.  This gets rid of
the YAGNI-dict entirely.

alignment gimmick.  David Abrahams notes that the standard "long double"
actually requires stricter alignment than "double" on some Tru64 box.
On my box and yours <wink>, it's the same, so no harm done on most
boxes.

Use posixly correct sort args.

Bugfix candidate.

- Use substring search, not re search for user-agent and paths.
- Consider * entry last. Unquote, then requote URLs.
- Treat empty Disallow as "allow everything".
Add test cases. Fixes #523041

bug #521526.

Doc/README is odd; it assigns some copyright to the PSF in 2000, when
I didn't think it existed...

There were never tests for the fact that list() always returns a *new*
list object, even when the argument is a list, while tuple() may
return a reference to the argument when it is a tuple.  Now there are.

This commit doesn't include the cleanup patches for stringobject.c and
unicodeobject.c which are shown separately in the patch manager.  Those
patches will be regenerated and applied in a subsequent commit, so as
to preserve a fallback position (this commit to those files).

Windows: apply normcase() as well as abspath().  (Note: this isn't
needed to make IDLE work, but it's a good idea anyway.)
