Summary: "unicode_escape" and "raw_unicode_escape" encoding is broken

Initial Comment:
In Python 2.4.2 and Python 2.4.1 (Windows XP)

>>> "\t\\t".encode("string_escape")
'\\t\\\\t'

>>> "\t\\t".encode("unicode_escape")
'\\t\\t'
>>> "\t\\t".encode("raw_unicode_escape")
'\t\\t'
>>> u"\t\\t".encode("unicode_escape")
'\\t\\t'
>>> u"\t\\t".encode("raw_unicode_escape")
'\t\\t'

I would have expected all to produce the same result.

Also round-tripping with the encoding doesn't seem to work:
>>> "\t\\t".encode('string_escape').decode('string_escape')
'\t\\t'
>>>
u"\t\\t".encode('unicode_escape').decode('unicode_escape')
u'\t\t'

Thanks
   Mark

Attached a patch. It looks like a simple typo. :)
