Summary: str.translate does not check table len

Initial Comment:
If you call str.translate without supplying the optional 
deletechars parameter, translate does not check to see if 
the table parameter has length 256.  For example:

Python 2.2.2 (#37, Oct 14 2002, 17:02:34) [MSC 32 bit 
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more 
information.
>>> s = 'hello'
>>> s.translate('')
'\x00\x00\x00\x00\x00'
>>> s.translate('', '5')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ValueError: translation table must be 256 characters long
>>>

Here's a patch using the latest stringobject.c (which I 
downloaded from the CVS browser, so the date of the original 
file is wrong.  The original should be rev. 2.198).
