Extending from three to four roughly equal chunks introduces three new
split boundaries - 3.3 4.3 and 4.18, but is trivial to hook in.
This gets chunks down to roughly 1/2G and with the resulting loss of
compression efficiency, it doesn't seem to make sense to support
splitting things any further. See the chunk sizes in the commit.
Document the new variable and its allowed value range since we don't
see adding any further split options.
