[issue4540] typo in a module describes utf-8 as uft-8

[dariusp]

dariusp <dariusp at internode.on.net> added the comment:

This appears to be the same issue as described in 5453 in which I
supplied a patch for release30-maint and py3k branches.

It's probably useful to address both issue 4540 & 5453 at the same time.

I would have added to this issue, but I didn't see it when I raised 5453.

On a side note, the line importer.find_module(modname) in pydoc.py line
1925 appears that it may return None.  If this is the case then the None
return value should be handled.
