OK.  I'll rebase on 106d710b and try to get the series out in a day
or two.

Agreed, except I don't think its going to save us very much (~4%)
and its enough of a change still to make things a little ugly.
If the "true" dictionary compression idea has any value it may
save us even more and make it easier to implement fast full text
searching across files.  But its definately more complex.  So I'm
going to shut up now.

No worry there.  I won't have enough time between now and the end
of this month to create a dictionary pack that's even ready for pu,
let alone next.  I hope we see 1.4.3 before then.  :-)
