Yes, but I wasn't talking about using $IFS for records (which is just dandy),
I was talking about the earlier example on the page for coping with spaces in
filenames.

BTW, you know that this:

  while read inline </etc/passwd
  do
  ...
  done

will repeatedly read the first line, versus:

  while read inline
  do
  ...
  done </etc/passwd

which reads the lines in sequence? I know you do, but plenty of other
folks won't notice.
