needforspeed: partition for 8-bit strings. for some simple tests,
...
this is on par with a corresponding find, and nearly twice as fast
as split(sep, 1)
full tests, a unicode version, and documentation will follow to-
morrow.

Added overflow test for adding two (very) large strings where the
...
new string is over max Py_ssize_t. I have no way to test it on my
box or any box I have access to. At least it doesn't break anything.

Fixed problem identified by Georg. The special-case in-place code for replace
...
made a copy of the string using PyString_FromStringAndSize(s, n) and modify
the copied string in-place. However, 1 (and 0) character strings are shared
from a cache. This cause "A".replace("A", "a") to change the cached version
of "A" -- used by everyone.
Now may the copy with NULL as the string and do the memcpy manually. I've
added regression tests to check if this happens in the future. Perhaps
there should be a PyString_Copy for this case?

Teach PyString_FromFormat, PyErr_Format, and PyString_FromFormatV
...
about "%u", "%lu" and "%zu" formats.
Since PyString_FromFormat and PyErr_Format have exactly the same rules
(both inherited from PyString_FromFormatV), it would be good if someone
with more LaTeX Fu changed one of them to just point to the other.
Their docs were way out of synch before this patch, and I just did a
mass copy+paste to repair that.
Not a backport candidate (this is a new feature).

Use Py_ssize_t to hold the 'width' argument to the ljust, rjust, center and
...
zfill stringmethods, so they can create strings larger than 2Gb on 64bit
systems (even win64.) The unicode versions of these methods already did this
right.
