It depends on what you're trying to do. The author of that wiki page
wanted to be able to comment-out blocks of code in a unified way
without having to know the comment character(s) for the language in
use. Vim still does not have a built-in solution to that problem.
Vim does know how to recognize the comment characters and styles of
different languages, though, by means of the 'comments' option,
which is often set by a filetype plugin. See
