[PATCH 16/26] update-ref --stdin: Harmonize error messages

From
Michael Haggerty <mhagger@alum.mit.edu>
Date
Mar 10, 2014, 12:46 UTC
Message-ID
<1394455603-2968-17-git-send-email-mhagger@alum.mit.edu>
In-Reply-To
<1394455603-2968-1-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 still have their old form, because $COMMAND and $REFNAME aren't passed all the way down the call stack.

Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu>

Making more error messages conform to the new pattern is an exercise
left to the reader (or maybe the writer if I find time to get back to
it).
