man pages must still work minimally

[Dan Jacobson]

$ man ls
       --author
              print the author of each file
$ ls --author
nurd.txt

Therefore the man page isn't accurate unless you place a statement
at top that one must read the whole page first before using anything.

You might as well say "see the Info page" at top instead of bottom.
P.S., empty lines seen intruding:
       --dereference-command-line-symlink-to-dir
              follow each command line symbolic link

              that points to a directory

       --sort=WORD
              extension -X, none -U, size -S, time -t, version -v

              status -c, time -t, atime -u, access -u, use -u
