| so why not say so and avoid the problem of using these components.

Becase the "fiddling with memory" part is a real mess, and
unnecessarily complicates the coding of the core algorithm.  The
alternatives are to use obstack, which are even messier.

Actually, I was not even considering std::vector from a language point
of view, I was speaking as a C++ user.  Realistically, one needs to
maintain a variably-sized array of strings which is a very low level
abstraction (from user point of view).
