correction to list of option names

[Iain Calder]

I found some errors in the table of long options in the
GNU coding standard at:

  http://www.gnu.org/prep/standards/standards.html

Old text:
   `file'
          `-f' in info, gawk, Make, mt, and tar; `-n' in sed; `-r' in touch.
New text:
   `file'
          `-f' in info, gawk, sed, make, mt, and tar.
   `reference'
          `-r' file to use as timestamp source in touch.

Explanation:
* The option to specify a script file in sed(1) is -f,
  same as for gawk, make, etc.  sed's -n option does
  something else.
* Also, make(1) is misspelled.  It should be lower case.
* Finally, the long option name for touch(1)'s -r option
  is --reference.  touch doesn't have a --file option,
  The cause of the confusion is probably that the argument
  to -r is a file.
