[PATCH v2 0/3] Easier access to index-v4

[Thomas Gummerer <t.gummerer@gmail.com>]

Hi,

previous round was at $gmane/242198.

Thanks to Junio, Eric and Duy for comments on the previous round.

Since then I've squashed the fixes suggested by Junio, added a test
showing what should happen if an index file is present and
GIT_INDEX_VERSION is set and fixed the typo found by Eric.

Thomas Gummerer (3):
  introduce GIT_INDEX_VERSION environment variable
  test-lib: allow setting the index format version
  read-cache: add index.version config variable
