Update: Finish fixing iki_read for runtime tests.

Update: Finish fixing iki_read for runtime tests.

The iki_read must still print the unmatched variables.

The `iki_read_process_line()` is indeed still valid to have.

The total should still be printed even when there is no data or the start range is out of range.
This ensures that a 0 is printed in these situations.

There may or may not be eki_read fixes needed but runtime tests do not exist for that yet.
A follow up commit shall address this.
