I wonder how that works.  Generally, the undo history belongs to a
buffer content different from the content after reverting.  Does your
patch prevent surprises like "undoing" changes that were never made to
the newly read-in buffer content?

Reading all of this thread, there were very few arguments about the
subject itself.  Which advantage does this change offer?  Just curious.
