[New-bugs-announce] [issue38097] cmd.Cmd: Allow other readline completion methods

[Mann Jani]

New submission from Mann Jani <mann4jani at gmail.com>:

readline has completion methods other than `complete` such as `menu-complete` or `menu-complete-backward` which behave differently.
Currently Cmd class has hardcoded `complete` method to the completion key which means trying to use other methods is not possible in a derived class without re-implementing cmdloop, or using some other crazy workarounds.

IMO Cmd.__init__ should take another argument named completionmethod with the default value of "complete" so that existing usage is not broken but it is possible to pass other values.
