Doug Bell 3f3d0cea61 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].
