Currently, running pydoc on a module will show you the documentation on 
all regular methods, and all special methods (starting and ending in 
double underscores).

Private methods (starting with a single underscore) are not included.

Some times, it would be nice to include docs for these methods aswell, 
and a small change to pydoc.visiblename solves the problem.

I've included a patch that adds this behaviour as an option (-i for 
include private names). The implementation isn't as clean as one would 
hope for (sets a global flag), but was the best I could come up with in 
the short time I had available. Feel free to make a better 
implementation.

The patch is against python 2.5.
