faster-format.patch: Patch for Python 3.3 optimizing str%args and
str.format(args), use _PyUnicodeWriter deeper in formatting. The patch uses
different optimizations:
* if the result is just a string, copy the string by reference, don't copy it
by value. It's not something new, this optimization was already used by the
PyAccu API. Examples:
- "{}".format(str)
- "%s".format(str)
* avoid a temporary buffer to format integers (base 2, 8, 10, 16). Examples:
- "decimal=%s".format(int)
- "hex=%x".format(int)
- "%o".format(int)
- "{}".format(int)
- "{:x}".format(int)
* don't overallocate the last argument of a format string. Example:
- "x=%s".format("A" * 4096)
