It is possible: just redefine POOLallocHTLine to allocHTLine (see pre dev.11
version for this macros, and HText_free), define POOLfreeHTLine and use it
as it was in my previous letter, and finally restore free loop in
HText_free().

Currently, we double the space in the worst case (=each line is in Stbl).
This is not bad having in mind that most documents have smaller tables,
and 2^N malloc implementations waste 1/4 space at average. Plus performance.

The situation differs if you need multiple passes for your improved table
support.
