* in finish, the replacement string referenced an unset variable (rha)
* loadfile would try to load a file if the varval had been set to "" (rha)
- * '$n' in variable values was being stripped by subst in PHP 4.0.4+ (John Mandeville)
- * '\n' was also being stripped. Fix by replacing with &#(36|92); in set_var and unreplacing in finish (rha)
* in get_undefined, only match non-whitespace in variable tags as in finish. (Layne Weathers & rha)
