This feature would permit passing None as the first
argument to str.translate in place of an identity
translation
table like ''.join([[chr(i) for i in xrange(256)])

This should be handy for deleting characters, e.g., as in

     s = s.translate(None, delchars)

[rhettinger]

Done. See revision 54772.
