[PATCH 0/5] Clarify "refs"

So here is a miniseries to update various parts of the documentation that still talk about $GIT_DIR/refs/. They are split into small and non-overlapping pieces so that any of them can be discarded more or less independently.

Thanks in advance for comments.

Junio C Hamano (5):
  check-ref-format doc: de-emphasize the implementation detail of a ref
  git.txt: de-emphasize the implementation detail of a ref
  glossary: update description of "tag"
  glossary: update description of head and ref
  glossary: clarify description of HEAD
