No doubt. People have done it both ways in the past, but I think
currently there's a weak consensus in favor of using one line for
such messages even when it runs past 80 columns, mainly because
that makes it easier to grep the source code for a message text.
But: I don't see too much value in changing this particular instance,
because the line break is in a place where it would not likely cause
you to miss finding the line. You might grep for the first part of
the string or the second part, but probably not for ", which is not".
If the line break were in the middle of a phrase, there'd be more
argument for collapsing it out.
