Progress: basic list write, with minor basic list read and extended list read changes.

Progress: basic list write, with minor basic list read and extended list read changes.

The basic list object write should only handle escaping slashes when it would be escaped.
Make sure to return an error when a newline is found.
Note that the stop point designates the end of the object so if the end of the object ends in slashes, then these must be escaped.

Perform some cleanups that I felt like doing while working on this.
