The function `format_display()` is used to print a single reference update to a buffer which will then ultimately be printed by the caller. This architecture causes us to duplicate some logic across the different callsites of this function. This makes it hard to follow the code as some parts of the logic are located in one place, while other parts of the logic are located in a different place. Furthermore, by having the logic scattered around it becomes quite hard to implement a new output format for the reference updates. We can make the logic a whole lot easier to understand by making the `format_display()` function self-contained so that it handles formatting and printing of the references. This will eventually allow us to easily implement a completely different output format, but also opens the door to conditionally print to either stdout or stderr depending on the output format. As a first step towards that goal we move the formatting directive used by both callers to print a single reference update into this function.
