This mailing list is the only place I can think of where I could possibly share this article:
"Emacs and Vi have been battling for text-editor supremacy among programmers for 40 years."

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).
Maybe this would work better...
%s/.*/"&"/
It's a lot briefer, and IMHO, more obvious.
Computer Scientists (and old-time vi aficionados) love to optimize things like this... :)

In other words, the author ignored "boundary conditions" - touché! Or is this more like a "degenerate case"?
