- quote name of referenced parameter in error message to ease reading - new parameter checker "parameter", performing an approximate checking for valid parameter specs - set NSF_ARG_CHECK_NONPOS only when there are multiple arguments - remove space checking for NSF_ARG_CHECK_NONPOS in favor of parameter checker
- nsf.c: aquire parameter structure for returns more lazyly (otherwise, a serializer handling returns would aquire the structure for every argument) - extend regression test
