[PATCH v2 0/4] diff --cc: relax path filtering

Fixes:
* test renamed and commit message rewritten, so that
  it mentions 3-parent merge rather than other uses
* test: fix && chaining and do at new line
* use postincrement in C code

Max Kirillov (4):
  t4059: test 'diff --cc' with a change from only few parents
  combine-diff.c: refactor: extract insert_path()
  diff --cc: relax too strict paths picking
  t4059: rewrite to be adaptive to hunk filtering
