So this is an example journal just tracking a pension (employer pays in with cash, pension automatically buys as many "units" of an investment fund PEN as it can)
What I'm not getting is how to get the current value to display correctly with `hledger bal -V`
here you've got an opening balance of PEN 500, plus 110 and 105 later, for a total of `PEN 715`
and the `P` statement at the bottom should value `PEN` at 98 pence
so the value in £ of the pension should be "£700.70"

but instead I get £715?
