I just ran into a case where a generator passed to 
list.extend was raising the error "argument to list.extend
() must be iterable".  It turned out that code inside the 
generator was causing a TypeError.  This error was then 
caught by PySequence_Fast, which remapped it to its 
error string parameter.

Attached is a modified PySequence_Fast which should 
avoid this kind of masking.

I'm accepting this for Py2.4 but doubt that it should be
backported to Py2.3.  Since only the message changes, no
ones code will live or die by this one.

Thanks for the patch.

See Objects/abstract.c 2.123.
