- Subject: [PATCH 23/23] kconfig/[mn]conf: handle backspace (^H) key
- Backspace is not working on some terminal emulators which do not send the
- key code defined by terminfo. Terminals either send '^H' (8) or '^?' (127).
- But currently only '^?' is handled. Let's also handle '^H' for those
- terminals.
