Reviewed by Simon Fraser.

Normally in handleEndOfLine, we either have preserve/nowrap type of content with the the combination of a valid m_lastObject
and a null m_current.renderer (meaning end of content) or a valid m_current.renderer.
However due to some special SVG behavior (see isSVGText), we could end up here pointing to _after_ the last object (m_current.renderer() is null_ptr)
with seemingly breakable content.
