I discovered that the "show lots" window display these amounts _with_
the currency symbol, and so allows some visibility on that
information. From some tests I did, it seems your assertion is not
correct. The amounts, at least as shown by the "show lots" window,
seem to be in the currency of the account of the second split in the
transaction.

That is, if I enter:

assets:investments:foobar	5	21	105
assets:current assets:bank EUR				105

then the "a:c a:bank EUR" account is credited by 105 EUR, and the
"sell" in a:i:foobar is 105 EUR (shown as € in "show lots").

But if I enter:

assets:investments:foobar	5	21	105
assets:current assets:bank USD				105

then the "a:c a:bank EUR" account is credited by 105 USD, and the
"sell" in a:i:foobar is 105 USD (shown as $ in "show lots").


Which means that the same ledger shows in the same column amounts in
differing currencies, without labelling them with the currency. I'd
argue this is bad, and a bug.


Additionally, I tried, and putting a EUR buy transaction and a USD
sell transaction in the same lot breaks the capital gains/losses
computation, it just puts 0 capital gain/loss. That might, or might
not, be fixable (especially if you have trading accounts activated).
