coverity#708446 Unitialized scalar field

Not done in CtorInitFormatter, because the later is used
in SwTxtFrm::FormatOnceMore() to 're-initialize'
and is in unclear that it is OK to trash/reset bUnclipped
as that point.
So doing it in the construcotr itself garanteed
that bUnclipped is not left un-initialized
without risking messing with the semantic of use
in SwTxtFrm
