The thing is ... that paragraph is talking about the field width when put
into escapes.  Example: %4(size).  What %(putaddr) does is different;
it's using num to make line breaks.  Since this code has been broken
forever, it's always been wrong to put a 0 in there.  The documentation
for %(putaddr) doesn't say setting the width is optional.
