------- Additional Comments from Antti Koivisto <koivisto at iki.fi>
Instead of trying to make editing code efficient (which would be nice, but is
bit risky at this point) the problem can be more or less completely hidden by
dividing large text blocks over multiple text nodes. Shorter linebox lists are
faster to search.

Dividing is done for both text and html documents. Firefox seems to be dividing
large text nodes too (in html).
