   So strspn, perfect for what I need!   
      
   before:   
      
   int ok = 1;   
      
   if (strlen(colorSpec) == 4) {   
       for (int i = 0; i < 4; i++) {   
           char c = colorSpec[i];   
           if (c < '1' || c > '8') { ok = 0; break; }   
       }   
   } else ok = 0;   
      
   after:   
      
   strspn() returns the length of the leading substring   
   consisting ONLY of characters in the allowed set...   
      
   if (strlen(colorSpec) != 4 && strspn(colorSpec, "12345678") = 4) FAIL;
