If I start by --init-ing a new vault, I need to have the space to fit
it, which is what I'm trying to avoid ... and also it will take
significant time and bandwidth; the server is on a rented VPS, and
dirvish is at home.

But actually, I may be letting my desire for theoretical optimisation
get in the way of practicality. My mail store is only 2G; I have 227G
free in my dirvish bank, have decent bandwidth, and don't pay for
data. I should probably just init a new vault and archive the old one :-)
