Complained is probably not the right word. If the error was expressed
correctly, it could potentially have answered everything right then and

See this TortoiseSVN thread for an example of the sort of side effect
problems this can cause, and why you might want to throw an error. TSVN
would have handled this much better if there had been an error.
