$ python
Python 2.3a1 (#1, Jan  2 2003, 22:36:29)

>>> 'a'.index('b')
Traceback (most recent call last):

ValueError: substring not found

str.index()/str.rindex() exception message contains
"in string.(r)index", but
unicode.index()/unicode.rindex()
doesn't.

For me, unicode message is more clear, and it is
consistent with other string methods which raises
exception, for example;

>>> 'a'.split('')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ValueError: empty separator
>>> 

2.2.2 has the same issues.
