Bugfix: The FSS Embedded Read is incorrectly handling empty Content.

The empty Content is being incorrectly handled as noted in the 0.6 commit 93a70bece8ecdb30801744e492fec8bb2601d2a4.

The '}' gets printed on empty Content, which is invalid.
Set the range to out of range when the start position is the line start.
This should only happen for empty Content because valid Content is only closed when '}' is on its own line.
