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

[Michael Haggerty <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.

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).
