[C++-sig] [patch] STL input iterator does not propagate exceptions

[Andreas Klöckner]

Hi all,

I get a segfault if I use boost::python::stl_input_iterator from C++, and the 
Python code (a generator or some such) that I iterate off of raises an 
exception (such as KeyboardInterrupt, which makes it easy to test). This is 
because a NULL return from PyIter_Next is always interpreted as "end of 
list", and not as the error that it may well be.

Attached patch fixes this.

Andreas
