        (line_info::has_block): Likewise.
        (struct source_info): Add new member index.
        (source_info::get_functions_at_location): New function.

        (add_line_counts): Assign it either to global of function scope.
        (accumulate_line_counts): Isolate core of the function to
        accumulate_line_info and call it for both function and global
        scope lines.
        (accumulate_line_info): New function.
        (output_line_beginning): Fix GNU coding style.
        (print_source_line): New function.
        (output_line_details): Likewise.
        (output_function_details): Likewise.
        (output_lines): Iterate both source (global) scope and function
