Patch by Michael Scharf. He writes:
The module cmd requires for each do_xxx command a help_xxx
function. I think this is a little old fashioned.
Here is a patch: use the docstring as help if no help_xxx
function can be found.
[I'm tempted to rip out all the help_* functions from pdb, but I'll
resist it. Any takers? --Guido]
