From 3f3d0cea61aba6ac2fef16736ef55e04bb735e02 Mon Sep 17 00:00:00 2001 From: Doug Bell Date: Tue, 16 Jul 2013 19:05:14 -0500 Subject: 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].
