Merge branch 'jk/index-pack-maint'

"index-pack --strict" has been taught to make sure that it runs the
final object integrity checks after making the freshly indexed
packfile available to itself.

* jk/index-pack-maint:
  index-pack: correct install_packed_git() args
  index-pack: handle --strict checks of non-repo packs
  prepare_commit_graft: treat non-repository as a noop
