Bugfix: revert slash improvements in FSS object read

Oops.

When relocating this I completely forgot that an object starting with something other than a double quote or single quote can never be a quoted object.
Therefore only the first slash needs to be delimited.

I need to update the FSS documentation to avoid this oops again.
This will be tacked on to the todo list for when I do my extensive review of the FSS processing code.
