Merge branch 'ds/blame-on-bloom'

"git blame" learns to take advantage of the "changed-paths" Bloom
filter stored in the commit-graph file.

* ds/blame-on-bloom:
  test-bloom: check that we have expected arguments
  test-bloom: fix some whitespace issues
  blame: drop unused parameter from maybe_changed_path
  blame: use changed-path Bloom filters
  tests: write commit-graph with Bloom filters
  revision: complicated pathspecs disable filters
