Wow, I haven't seen such a blunt and unhelpful RFTM comment for a while. This comment is inappropriate in so many ways:
1) The unix systems have an inconsistent documentation mix of man pages, info pages, "-h", "-help", "--help", HTML docs, separate manuals (e.g. Debian Administrator's Handbook) and so on.
2) "man foo" leads to: "No manual entry for foo"
3) "man vi", as well as "man vim" both lead to a manpage that has no EXAMPLES section at all (see https://www.freebsd.org/cgi/man.cgi?query=vi, https://www.freebsd.org/cgi/man.cgi?query=vim)
4) The Vi(m) manpages explain only the command line arguments, not the editor commands. The latter are available by typing ":help" in the editor.
