 * Synopsis:
 *   Given a list of problem report numbers, create the tex file that

 *          and printed.  This function will return NULL if the list
 *          is empty. 
 *   msg_win : pointer to widget where messages should go (can be NULL)
 *
 * Outputs:
 *   None.
 * 
 * Return Value:
 *   The full path of the created tex file (without the '.tex' extention)
 *   if success, NULL otherwise.  Remember to g_string_free it somewhere
 *   if we return non-NULL.
