[new code version deleted]

i got caught by the #oldFileNamed: bug.  there was one additional step,
let's call it 3a.  open an inspector on SourceFiles and make sure that the
rwmode for each of the StandardFileStreams (.changes and .image) is set
to true.  then, evaluate step 4 and proceed.  if i didn't make that change
to the respective rwmodes, i continued to get the file error.

i am not clear on why the close/open step didn't seem to reset these
Booleans -- i just made the patch to save the image and i plan to
investigate the "whys" later.

thanks for the indenting feature, Reinier,  -John
