- nsf.c / ListCmdParams(): Fixed a crash scenario when relying on the methodName for trying to resolve the parametersyntax for C-implemented commands. In these cases, methodName stands for a null pointer, so we need to fall back to Tcl_GetCommandName(). - nsf.tcl / ::nsf::mixin: The proc implementation used "mixin" rather than "class-mixin" as (default) relation type.
