This is because there really is a difference between the two errors, and
"git update-ref" tries to emit distinct error messages for them:

* "zero new value" means that the new value was 0{40}
* "missing <newvalue>" means that the new value was absent

The problem is that it is not distinguishing between these two cases
correctly, and fixing *that* is more than a one-liner.
