I don't see why revert-buffer would be singled out, since many
different commands cause buffer changes.

If it were implemented, it may be better to generalize it to allow
any undo to have an annotation of what caused the change. Then the
user would set a defcustom for whether to echo an undo's annotation
while undoing. I could foresee Undo Tree's visualization displaying
the annotation next to its nodes.
