Subject: [PATCH] Fix confusing git-update-ref error message
Message-ID: <20051110195513.25573.31064.stgit@machine.or.cz>
URL: https://gitlist.dev/e/20051110195513.25573.31064.stgit%40machine.or.cz

```
When git-update-ref has hit the "Ref %s changed to %s" error, I just stare
at it, left puzzled. This patch attempts to reword that to a more useful
and less confusing error message.
