[New-bugs-announce] [issue35270] Cmd.complete does not handle cmd=None

[daniel hahler]

New submission from daniel hahler <python-bugs at thequod.de>:

When `parseline` returns `None` for `cmd` (like pdb++ might cause it when changing a cmd "disable" to "!disable"), the following will cause a TypeError:

> compfunc = getattr(self, 'complete_' + cmd)

"None" should be also forwarded to "completedefault", just like cmd="".
