Similar to --form except that the value string for the named parameter is used
literally. Leading '@' and '<' characters, and the ';type=' string in
the value have no special meaning. Use this in preference to --form if
there's any possibility that the string value may accidentally trigger the
'@' or '<' features of --form.
