What about printing the \r at the beginning of the status message
instead of at the end? For sucessive status outputs, either way works,
but the cursor will be at the end of the status message so it won't be
overwritten if something else is output after it.
Of course this has the downside that the status message will overwrite
whatever was at the beginning of the current line, but I expect that
requiring a newline at the end of each warning/error message is sensible
