New submission from STINNER Victor: Attached patch adds tests to check that str%args and str.format(args) take all optimization opportunities for simple format strings. It takes also the fast-path when Unicode string argument when width and/or precision is set. For example, "%.3s" % "abc" now returns "abc" unmodified (instead of creating a copy). The patch also takes the fast-path when formatting integers with str%args when the argument is not an int, but an object with __int__ method.
