Most. The documentation starts with:

        dired-use-ls-dired is a variable defined in `dired.el'.
        Its value is nil
        Original value was unspecified

So GNU Emacs started with a promising value, "unspecified". It then found that 
ls is not right, and it then did not find – or search for – gls, because 
"unspecified" was reset to nil. Why did it so? What is the reason for the 
failure? In GNU Emacs 24.0.50

Maybe I thought it would teach GNU Emacs to use the right programme. Probably I 
found this was faulty because the line is commented with a ";" – and no text in 
my init file. What seemed to have worked once (in GNU Emacs < 24) are these two 
lines from my site init file:

        (setq ls-lisp-use-insert-directory-program t)
        (setq insert-directory-program "gls")



There's something the technicians need to learn from the artists. If it isn't 
aesthetically pleasing, it's probably wrong.
