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?

now about 3x faster on my machine, for the replace tests from string-
bench.

(the unicode versions of these are still 2x faster on windows,

based on work by Andrew Dalke, with tweaks by yours truly.

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).

Py_ssize_t issue; repr()'ing a very large string would result in a teensy

string, because of a cast to int.

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.

More low-hanging fruit. Still need to re-arrange some code (or find a better

solution) in the same way as listobject.c got changed. Hoping for a better
solution.

Use macro versions instead of function versions when we already know the type.
...
This will hopefully get rid of some Coverity warnings, be a hint to
developers, and be marginally faster.
Some asserts were added when the type is currently known, but depends
on values from another function.
