> Describe the enhancement and the motivation for it.
Suppose I'm looking at a diff where someone moves 10 lines from fileA.c to fileB.c. I'd like to look at sections of those files side by side, so that I can make sure nothing changed during the move.
It'd be cool if I could, for example, select a chunk from left column ("Revision X") and a chunk from the right column ("New Change"), and then have RB render an instant side-by-side diff between the two.
