octave-lyh: libinterp/parse-tree/oct-parse.in.yy annotate

annotate libinterp/parse-tree/oct-parse.in.yy @ 17324:8e2906e2fb26

avoid reduce/reduce conflict in parser rules * oct-parse.in.yy (return_list): Don't accept multiple values outside of square brackets by using identifier instead of return_list1. * pt-misc.h (tree_argument_list::tree_argument_list): New constructor with tree_identifier* as argument. * test/nest/varg_nest2.m: Fix syntax of function declaration.
