Documents with many lines overallocated pagination info.
There is an object LineFragmentationData that is used for pagination
that is created on demand. That object was created for normal documents
and cost roughly 32 bytes per line, adding up to 3-5 MB on a big text
document (5% of all memory usage).
Testcase: http://norvig.com/big.txt - 3-10 MB RAM savings.
I don't know what I'm doing but this patch prevents the allocation and
saves the memory.
