Done in commits ending with 8220. Illustrated in 
examples/pylab_examples/histogram_demo_extended.py.
Thanks for your work on this.
(There is probably quite a bit more cleanup and refactoring that could 
be done. Much of the plotting capability of hist could be factored out 
for other uses, for example.)

Hi Peter,
Your previous addition looks fine here. Keep pinging probably someone should
commit your additions.
I would like to see your further editions. Maybe you can use google-code or
somewhere to host the code and continue making additions there. Once some
important steps are completed changes can integrated into matplotlib back.
