[PATCH v3 0/3] "diff --color-moved" with different heuristic

These patches are on sb/diff-color-move.

Patches 1 and 2 are unchanged.

If we're planning to cook a heuristic, we might as well try a better one. What do you think of this? A heuristic of number of non-whitespace characters, applied at the block level, and not dependent on the block's neighbors.

As for the test, good point about testing the boundary conditions - I have included another test that does that.

Jonathan Tan (3):
  diff: avoid redundantly clearing a flag
  diff: respect MIN_BLOCK_LENGTH for last block
  diff: define block by number of non-space chars
