The impetus for introducing this binding now is that we have two cases
of a non-special mode with a (very) useful `revert-buffer' binding, so
we can't use `g' there.  So it's time to give it a global binding.

But I disagree that it's not a useful general command for non-power
users: A common question is "how do I reload a file?", and we didn't
have a key binding for that.  `C-x C-f' does not reliably reload a file,
since it has DWIM stuff going on.

So giving the command a global binding fixes both these things.
