[BZ#738700] Add "Patience Diff" diff
Submitted by Konstantine Rybnikov
Link to original bug (#738700)
Description
There's wonderful diff algorithms called Patience Diff 0, which is used, for example, by tool called patdiff 1. It seems to be much more developer-friendly, so I'd like to propose to use that, either as an option or just as main algorithm (not sure what's best).
Thanks!
