Can we compare two sequent lines in one file? A sample file can be found at the bottom.
With my friend's suggestion, I have managed to do this by calling an internal function(ediff-regions-internal) of ediff.el.
However, leveraging internal interface is quite dangerous. Besides, this is still some more effort to make it work with the way of ediff-regions-internal. I may even have to change the code of ediff.el!
I am referring to my super heroes in the mail list. Can anyone give me a hint for a better way?
