This is a small patch to the Lib/pydoc.py implementing
command line editing capabilities (and optional
readline support) for the help() builtin.

The patch was small, but I've tried to make it even smaller.
Introducing a subclass seemed unnecessary to me, I just used:

if self.input is sys.stdin and self.output is self.stdout:

in getline(). I'll check this in if you don't have any
problems with my patch.

Ok, I think it's reasonable compromise for now. :-)

Ok, checked in as rev 1.95 of pydoc.py.
