show-ref: make --head always show the HEAD ref
The docs seem to say that doing git show-ref --head --tags would show both the HEAD ref and all the tag refs. However, doing both --head and either of --tags or --heads would filter out the HEAD ref. Also update the documentation to describe the new behavior and add tests for the show-ref command. [jc: Doug did proofread the tests, but it was done by me and bugs in it are mine].
