Suppose one makes a C extension type that is callable and has a 
__doc__ attribute. Currently, calling help() on the object yields 
something like the following: 
 
>>> help(scipy.linalg._flinalg.slu_c) 
Help on fortran: 
 
<fortran object> 
>>> hasattr(scipy.linalg._flinalg.slu_c, '__doc__') 
True 
>>> 
 
help() could give more useful information by modifying 
pydoc.TextDoc.docother to check for a __doc__ attribute and add it 
(just as docother checks for the 'doc' keyword).
