No, it's just that `where-is-internal` by-and-large doesn't run the
`:filter`s when doing its search, so instead of seeing a binding to
`ignore` it will see a binding to an empty keymap.

As we've seen `where-is-internal` does end up running the `:filter`
sometimes, but it's only done on those few bindings that match.

When building a menu, the `ignore` or the empty keymap won't be used at
all (their only use will be to pass them to the `:filter` function,
which ignores that argument).  That's why the "binding" is currently
called `ignore`: not because we want to use the `ignore` command but as
a way to say "this is not used".
