Mac OS terminal * `ruby -v`: ruby 3.1.2p20 * `rdbg -v`: rdbg 1.5.0 **Describe the bug** I noticed that `^k` and `^y` work (kill-line and yank) as expected, but was surprised that ^u (unix-line-discard) does not. **To Reproduce** 1. enter debugger 2. type anything 3. control-u **Expected behavior** Everything to the left of the cursor should be cleared back to the prompt
