Note that the author's vi example to put quotes around lines: %s/(^|$)/"/g only works if ^ .ne. $, that is, the line is nonempty. (Sorry, mathematicians just love to point out things like this).
In other words, the author ignored "boundary conditions" - touché! Or is this more like a "degenerate case"?
