Update: Better handle comments in FSS and fix problems.

Comments may exist inside of an FSS Basic List and FSS Extended List.
Handle the comments.

The FSS Basic List Read and FSS Extended List read both need to print the ignore character around content in pipe mode.
The FSS Extended List needs to specifically not do this for individual nested objects.

Fix problems in the FSS Basic List read content handling when an object is found such that content is empty.
Clean up some of the code, doing some basic code simplification.
The FSS Basic List Read should always return a range and should not exclusively end always at an EOL.

Fix a case where not enough memory is allocated for delimits in FSS Basic List.

Add missing/incomplete parameter checks.
