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. Signed-off-by: Changbin Du <changbin.du@gmail.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
