Naturally, we could have a customization point that supports several 
displays (like xref-show-xrefs-function), but in this case as well any 
new display would have to reimplement almost all functionality (I guess 
that's unavoidable), and the format of the input data (CHANGES) need to 
be usable for such different displays.

I can roughly understand how to produce a diff from a list ((FILE 
START-POS END-POS NEW-TEXT) ...), but it seems more difficult to do the 
reverse. Though also possible, I suppose.
