- Remove another potential sources of infinite loops caused by EOF in 

the middle of the font and color tables.
- Closing brace on text level is treated as EOF (effectively
  protecting the control from trash after the end of RTF).
- Removed misleading comment about incomplete buffers (I was
  definitely wrong).
