+- When x is an object whose class implements __mul__ and __rmul__,
+ 1.0*x would correctly invoke __rmul__, but 1*x would erroneously
+ invoke __mul__. This was due to the sequence-repeat code in the int
+ type. This has been fixed now.

- Previously, "str1 in str2" required str1 to be a string of length 1.
This restriction has been relaxed to allow str1 to be a string of
any length. Thus "'el' in 'hello world'" returns True now.
