Patch by Ori Avtalion to fix a minor display glitch in the RightArrow.

no code changes.

the tests.  This stops the confusing/annoying:

    No handlers could be found for logger "cookielib"

message we got whenever some test running after test_logging
happened to use cookielib.py (when not using regrtest's -r,
this happened during test_urllib2; when using -r, it varied).

Will backport to 2.4.

returning 'a' as the delimiter.  It now returns '|', but not because I
understood better what the code was supposed to do.  Would someone that
understands the idea behind _guess_delimiter() (see its doc string) look to
see if my fallback choice is better than before or if it's just serendipity
that I picked the proper delimiter?

Floating point literals don't work in non-US locale in 2.5.  Patch and
new locale tests by Hye-Shik Chang.

weakref object itself is deleted first.

A patch by mwh to check that user-defined mro's are reasonable
enough.

* set sq_repeat and sq_concat to NULL for user-defined new-style
  classes, as a way to fix a number of related problems.  See
  test_descr.notimplemented()).  One of these problems was fixed
  in r25556 and r25557 but many more existed; this is a general
  fix and thus reverts r25556-r25557.

* to avoid having PySequence_Repeat()/PySequence_Concat() failing
  on user-defined classes, they now fall back to nb_add/nb_mul if
  sq_concat/sq_repeat are not defined and the arguments appear to
  be sequences.

* added tests.

Backport candidate.

last field was empty it would strip the delimiter and incorrectly guess that
"" was the delimiter.  Reported in c.l.py by Laurent Laporte.  Will
backport.

precisely the motivation and the differences.

Added links to www.python.org/doc/newstyle.html and a footnote to warn against
the statement "x[i] is equivalent to x.__getitem__(i)", which already caused
many invalid bug reports on SF.

should depend on the pythoncore project.

All the --all test pass using -O on WinXP now.

- Get rid of pgen.c and tokenizer_pgen.c.

- Include tokenizer.c.

All the -uall tests pass on my WinXP VC7.1 box now.

cast first PyUnicode_Decode argument to proper type (why is
"char *" used for encoded byte streams, btw?  shouldn't that
be "void *" or, if necessary, "unsigned char *"?)

compiler warnings about mixing signed and unsigned types
in comparisons.

in _winreg.c.
