Hi Rob, Wasn't aware of your comments on diff, An algorithm by Hunt McIlory ( http://cm.bell-labs.com/cm/cs/cstr/41.pdf) is used for this diff implementation. Will have a look at Patience Diff and see if current implementation can be patched. regards, Ashwini On Mon, Aug 4, 2014 at 7:44 PM, Rob Landley r...@landley.net wrote: On 08/03/14 15:39, Bobby Bingham wrote: On Sat, Aug 02, 2014 at 11:39:21AM -0500, Rob Landley wrote: On 08/01/14 06:08, Ashwini Sharma wrote: Hi Rob, List, Attached are the new toys unified DIFF and USERDEL.
