Re: reporting maps

Hmm, maybe I'm not quite sure what you're asking, but you can definitely
remap `f` to whatever you want, overriding the default behavior. All I
was saying was that the built-in, default mappings for commands like `f`
and `I` do not correspond to functions that Vim exposes to the user, so
unlike mappings defined by the user, there's no way to display which
function they map to. I apologize if that's not what you were asking
about. :)
