Indeed.

This reminds me that I've often found it odd that there's no global
binding for `revert-buffer' -- I think there should be, because it's
such a useful command.

Sean suggested `C-c C-r', which is nicely mnemonic, and is natural as a
non-complicated alternative to `C-c C-f' when trying to reload a file
(since `C-c C-f' has a lot of annoying DWIM stuff going on).

We can't use `C-c C-g', I guess, since we try to avoid keystrokes that
involve `C-g' (since `C-g' should reliably quit), but that would also be
a natural keystroke, since `revert-buffer' is bound to `g' in
`special-mode'.

Any opinions?
