Ooh...not quite.  I put the weighted average basis on C3, which I think is
correct.  What acquisition date should I use?  I think the tax word is
"Various", but Beancount doesn't seem to like that.  Perhaps the best
choice is to use the latest of the underlying dates -- April, in this case
-- and add a note to treat the acquisition date manually on the tax return.

Sound reasonable?
