This isn't really a bug. It's caused by the extra ESC, which results in an unexpected keybinding being activated. I'm going to assume that, like mine, your left arrow key expands to ^[[D (ESC, left bracket, D). > - At the prompt type 0123456789 > - hit escape twice The first ESC takes to to vi command mode, and its keymap. The second introduces a multiple-key sequence, since `ESC' is bound to indirect into a secondary keymap in vi-command mode's keymap. > - press the left-arrow The first escape is taken as the second character in the multi-key sequence (ESC-ESC), which is unbound. The `[' is next, and it's unbound. Then comes the `D', which is bound to its standard vi meaning: delete from point to the end of the line. > - the '9' will be deleted and this is why. > - press escape again and do it again. > - press left-arrow again > - the '8' will be deleted > - etc...
