[PATCH v2 0/3] "update-index --show-index-version"

Even though there is "test-tool index-version", there wasn't an
officially supported way for end-users to inspect the index version
of an on-disk index.  Let's have one.

Junio C Hamano (3):
  update-index doc: v4 is OK with JGit and libgit2
  update-index: add --show-index-version
  test-tool: retire "index-version"
