String and unicode objects allow objects that  
implement the buffer interface to be used in  
method arguments where a string is expected in  
most cases - but it's not completely consistent.  
Examples where the buffer interface is ignored  
include all the strip methods, the format  
methods, the just methods (for strings but  not 
unicode) and the "in" operator (for strings but not 
The attached patch implements the missing

Are there any doc updates necessary?  If so that should be
included in the patch.
Tests need to be added to verify objects that implement the
buffer interface works for all affected code.

I don't think any doc updates are necessary. Those 
methods that don't need fixing don't have any 
documentation that is specific to objects that 
implement the buffer interface. 
Likewise for tests. I couldn't find any existing tests for 
objects that implement the buffer interface - maybe 
because the core doesn't include any objects that 
can be tested.

This looks like a useful addition for Python 2.x - not sure about 3.x,
since that doesn't have the 2.x buffer interface anymore.

Phil, could you update the patch for Python 2.7.

Yes I can update the patch, but it might be a while before I get the time.

This won't get applied anymore to 2.x.
