Bugfix: Valid comment lines are keeping leading white space.

Bugfix: Valid comment lines are keeping leading white space.

Any line that ends up being a valid comment line may have white space on the left.
For lists, such as FSS Basic List, the leading white space is being printed.
This is not correct at all.

This is easily solved by getting the last new line and add one.

Update the specification to make the expected behavior clear.

Cleanup comment lines and other related code while its convenient.
