`list -` doesn't work with IRB console

[AlexWayfer]

Your environment

• ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux]
• rdbg -v:rdbg 1.9.2

Describe the bug

Here is the list - command to see predecessor lines (useful after regular list usage).

It works in a default console, but not in IRB: it considers - as an operator, I suppose.

To Reproduce

1. binding.break in a code.
2. list in IRB console.
3. list - in IRB console.

Expected behavior

Working list - command (or an alias).
