- nsf.c: * add flags "-closure" and "-source" to "/cls/ info methods" (the cases for "/obj/ info methods" are already covered by "/obj/ info lookup methods") * extend regression test
nsf.c: - new cmd for debugging: nsf::__db_show_obj - added MethodDupInternalRep() and FlagDupInternalRep() since they appear to be required in Tcl 8.6b2.
