I'm not a SciPy developer so my weight on the discussion is next to 
zero, but I personally think that other people code breaking is not a 
good reason to keep a buggy function.

We don't want code that relies on bugs like they were features: we're 
not Microsoft, aren't we? ;)

People should be informed before updating, of course, and maybe an 
oldhistogram() function could be maintained to allow for easy updating, 
but if histogram() behavour is so flawed that people is forced to 
rewrite their own routines, please fix it.
