push: move unqualified refname error into a function

A follow-up change will extend this error message with the advice
facility. Doing so would make the indentation too deeply nested for
comfort. So let's split this into a helper function.

There's no changes to the wording here. Just code moving &
re-indentation, and re-flowing the "TRANSLATORS" comment.
