Specify whether to use 'Non-width Optional Breaks' when breaking long strings for wrapping.

The 'Non-width Optional Break' is a pseudo-symbol provided by MS Word (the RTF equivalent is '\zwbo') exactly for such situations: to specify where the text should be broken when it is wrapped. It has no effect when no wrapping is needed.

However, the problem with 'Non-width Optional Break' is that some RTF readers do not interpret it. Even MS Word 2000, where it can be found on the Insert | Symbol | Special Characters tab, actually ignores such breaks!

That's why this option was introduced. If wrapping of long nonbreaking strings does not work, try to unselect (false) this option. Then, the normal line breaks will be used.
