[PATCH 0/2 v4] xdiff: implement empty line chunk heuristic

Here we go. I squashed in your patch, although with a minor change:

-               if ((flags & XDF_SHORTEST_LINE_HEURISTIC)) {
+               if ((flags & XDF_COMPACTION_HEURISTIC) && blank_lines) {

We did not need that in the "shortest line" heuristic as we know a line with the shortest line length must exist. We do not know about empty lines though.

Thanks, Stefan
