Merge branch 'jk/bisect-show-tree'

"git bisect" makes an internal call to "git diff-tree" when
bisection finds the culprit, but this call did not initialize the
data structure to pass to the diff-tree API correctly.

* jk/bisect-show-tree:
  bisect: always call setup_revisions after init_revisions
