When AddCmd.Completer() returns an array with many strings, auto-completion prints a lot of text

Hi.

First, I would like to say that the ishell module is great and very easy to use
:)

Mu problem description:
I wrote a simple CLI and I added an auto-completion to one of my commands.
The command.Completer() method returns an array with many entries (~50K),
but there is a very low number of prefixes common to them.

When I press the "tab", after I'm writing the command token,
the auto-complete prints all those options, and this takes a lot of time...

Is there is a better way to handle this?
It would have been nice if only the prefixes would have printed and not all of the options.

Thank you
Dotan
