Hmm , I'm confused , I added the following but it fails to recognise the 
new option. Does that need to be added somewhere else as well?

gnuplot> set terminal svg mouse standalone name basename  font 
"verdana,9" size 800,600;
                                 ^
          "monthly.gnu", line 19697: unrecognized terminal option


[ The caret is indicating "standalone" ]





static TBOOLEAN SVG_mouseable = FALSE;
static TBOOLEAN SVG_standalone = FALSE;

   if (equals(c_token, "mouse") || almost_equals(c_token, "mous$ing")) {
       c_token++;
       SVG_mouseable = TRUE;
       continue;
   }

   if (equals(c_token, "standalone") || almost_equals(c_token, 
"stan$dalone")) {
       c_token++;
       SVG_standalone = TRUE;
