Subject: [RndTbl] The Oldest Rivalry in Computing

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... :)
