I think there are two issues:

1. If you don't enable `view-mode', you will see that in `tar-mode-map'
   both `e' and `f' are bound to `tar-extract'.

   However, when you enable `view-mode', only `e' is shadowed.

2. `0 .. 9' are technically shadowed, in the sense that there is a
   binding for them in an overriding keymap.  Only that in this case the
   binding in the other keymap is the exact same command.

So in conclusion the output here should probably be:

  0 .. 9	digit-argument
  e		tar-extract  (binding currently shadowed)
  f		tar-extract
