Harden CFDE_TextOut::m_ttoLines.

The libc++ hardening project has not yet added bounds checks to
std::deque<>, so being hardening instances of its operator[]().

-- fix initialization while at it (no reason to start with 5 empty
   elements, this is a mistake left over from a representation change
   long ago where 5 used to mean an initial reservation size).
