One drawback of this change is that messages such as the one you get
here are less obvious:

  M-: (ask-user-about-supersession-threat "foo") RET
  C-h

The help text now says:

    Usually, you should type ‘n’ and then ‘C-x x g’,
    to get the latest version of the file, then make the change again.

The "C-x x g" part used to be "M-x revert-buffer" and therefore more
self-explanatory.  (This is due to subsitute-command-keys replacing the
"\\[revert-buffer]" with the new keybinding.)

So perhaps this change should be accompanied with grepping our sources
for "\\[revert-buffer]" and looking over the relevant substitutions to
make sure the help is sufficiently clear?  I see 16 such matches.
