See http://www.venge.net/mtn-wiki/RevisionNumbering .
Heights are, basically, a way of caching the result of a topological sort of
all revisions. If r2 is a descendant of r1, then height(r2) > height(r1).
(Note that the reverse statement is this: if height(r2) > height(r1), r2 is
either a descendant of r1, or r1 and r2 are not related at all.)
