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

annotate libinterp/parse-tree/oct-parse.in.yy @ 23673:1d1ce4df5255

refactor bison rules for parsing functions * parse.h, oct-parse.in.yy: Expect 9 shift/reduce errors. (base_parser::make_function): New function. (function1, function1): Combine non-terminal rules with function rule. (opt_param_list): New non-terminal. (function): Combine rules as much as possible. Move all processing to make_function.
