annotate libinterp/parse-tree/oct-parse.yy @ 27764:f64e399b6dda

report missing semicolon location for array expressions (bug #57159) * parse.h, oct-parse.yy (base_parser::finish_matrix, base_parser::finish_cell, base_parser::finish_array): New args, open_delim and close_delim. Change all uses. (base_parser::finish_matrix, base_parser::finish_cell): Use close_delim location info for empty matrix/cell location info. (base_parser::finish_array): Use close_delim location info for array and constant location info.
