[PATCH v2 0/3] Fix how for-each-ref handles broken loose references

[Michael Haggerty <mhagger@alum.mit.edu>]

This is a reroll of [1]. Thanks to Peff and Junio for their comments
about v1.

Changes since v1:

* Use $_z40 to initialize $ZEROS in test.

* Test that "git for-each-ref --format="%(objectname) %(refname)"
  *doesn't* notice references that point at missing objects.

This patch series is also available from my GitHub account [2] as
branch for-each-ref-errors.
