[PATCH v3 0/4] Fix how for-each-ref handles broken loose references

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

This reroll addresses all of the comments about v1 [1] and v2 [2].
Thanks to Stefan, Junio, and Peff for their comments about v2.

Changes since v2:

* Simplify logic flow in read_loose_refs().
* Remove unnecessary call to hashclr() in read_loose_refs().
* Improve a comment and commit message.

This patch series is also available from my GitHub account [3] as
branch for-each-ref-errors.
