[issue7330] PyUnicode_FromFormat: implement width and precision for %s, %S, %R, %V, %U, %A

[STINNER Victor]

STINNER Victor added the comment:

Updated patch: precision for "%s" and "%V" (if the first PyObject* argument is NULL) formats is now a number of bytes, rather than a number of characters. width is still always a number of character.

The reason is that "%.100s" can be used for avoid a crash if the argument is not terminated by a null character (see issue #10833).
