I had similar thoughts as I was looking this over before sending it
out, but I couldn't think of a way to state this that would make
sense.  I felt sure that if I just changed "is an error" to "is
undefined or where an error would be signalled", somebody would be
sure to complain about it being wrong for explicit calls to ERROR.
Actually, I was hoping that if I left it alone, somebody else would
propose some alternate wording.  :-)

This was originally a suggestion from Kent Pitman, who probably knows
better than anybody what the ABORT restart was intended to be used
for.  You'll have to take it up with him, because I don't feel
qualified to argue about it one way or the other.
