[PATCH v3 18/27] update-ref --stdin: harmonize error messages

From
Michael Haggerty <mhagger@alum.mit.edu>
Date
Apr 7, 2014, 13:48 UTC
Message-ID
<1396878498-19887-19-git-send-email-mhagger@alum.mit.edu>
In-Reply-To
<1396878498-19887-1-git-send-email-mhagger@alum.mit.edu>

Make (most of) the error messages for invalid input have the same format [1]:

    $COMMAND [SP $REFNAME]: $MESSAGE
Update the tests accordingly.
[1] A few error messages are left with their old form, because
    $COMMAND and $REFNAME aren't passed all the way down the call
    stack.  Maybe those sites should be changed some day, too.
