This closes SF bug #550409.

Typo: whcar_t should be wchar_t.

Bugfix candidate? Don't know how this is handled in the docs.

Original patch(es):
python/dist/src/Doc/api/concrete.tex:1.15

Repair widespread misuse of _PyString_Resize.  Since it's clear people
don't understand how this function works, also beefed up the docs.  The
most common usage error is of this form (often spread out across gotos):

	if (_PyString_Resize(&s, n) < 0) {
		Py_DECREF(s);
		s = NULL;
		goto outtahere;
	}

The error is that if _PyString_Resize runs out of memory, it automatically
decrefs the input string object s (which also deallocates it, since its
refcount must be 1 upon entry), and sets s to NULL.  So if the "if"
branch ever triggers, it's an error to call Py_DECREF(s):  s is already
NULL!  A correct way to write the above is the simpler (and intended)

	if (_PyString_Resize(&s, n) < 0)
		goto outtahere;

(some tweaking for different _PyObject_GC_Malloc() call in 2.2. checked,
still returns the same thing on failure...)

_PyObject_GC_New:  Could call PyObject_INIT with a NULL 1st argument.
_PyObject_GC_NewVar:  Could call PyObject_INIT_VAR likewise.

(reported by François Pinard).
Added some missing "_" characters in the same cluster of productions.
Added missing floor division operator in m_expr production, and mention
floor division in the relevant portion of the text.

Make sure that tp_free frees the int the same way as tp_dealloc would.
This fixes the problem that Barry reported on python-dev:
   >>> 23000 .__class__ = bool
crashes in the deallocator.  This was because int inherited tp_free
from object, which uses the default allocator.

Second part of fix for #493826: regenerated suite modules so errn exists
but == 0 doesn't signal an error.

This also picked up a few other changes, but they should be harmless.

divmod &c. Should probably be cleaned up properly so that the tests
don't call that.

This adds the optional argument for str.strip
to unicode.strip too and makes it possible
to call str.strip with a unicode argument
and unicode.strip with a str argument.

Add a method zfill to str, unicode and UserString
and change Lib/string.py accordingly
(see SF patch http://www.python.org/sf/536241)

This also adds Guido's fix to test_userstring.py
and the subinstance checks in test_string.py
and test_unicode.py.

Deprecate % as well.  The message for deprecation of //, % and divmod
is the same in all three cases (mostly because // calls divmod :-).

Original patches were:
python/dist/src/Objects/complexobject.c:2.59

Add news about deprecated complex ops.

Original patches were:
python/dist/src/Misc/NEWS:1.387

SF bug #543387.

Complex numbers implement divmod() and //, neither of which makes one
lick of sense.  Unfortunately this is documented, so I'm adding a
deprecation warning now, so we can delete this silliness, oh, around
2005 or so.
