well, the problem is really that I do not want to quit and restart
ediff, find the difference region, etc...

I guess the best thing for me would be a command
"split-difference-region", that makes every (refined) difference a
single difference region.  Maybe a step into this direction would be
to make every line in the current region a region on it's own.  This
would already be quite helpful, I guess.

How are the difference regions computed?
