instead of deleting in "vi overstrike" mode? It's getting a bit annoying as I'm so used to using backspace to _back_space_.

You can look at rltty.c:_rl_bind_tty_special_chars() and modify it to
your heart's content.


The following patch checks that if vi-mode is in _overstrike_mode_, then it'll execute rl_backward_byte() instead of rl_rubout().

Backspace works now if erase is set to ^H instead of ^?.

Thanks for the pointer to get me started.
