Rather than running the tests of Emacs version N in historical versions 
before N, we can run them in future versions after N.  This is actually 
what happens naturally as the code evolves (assuming we run "make check" 
regularly), so it's very simple and requires no added effort.  (Of 
course, this doesn't work for tests written after the fact.)  As long as 
we don't touch a given test, we know that it's compatible.  If we have 
to modify it to keep it passing, we know that there was an incompatible 
change.
