Simon Michael eb75946e64 print: always right-align amounts
print now always right-aligns the amounts in an entry, even when they
are wider than 12 characters.

If there is a price, it's considered part of the amount for
right-alignment. Maybe it would be nicer to put amounts and prices in
separate columns ? That will get a little complicated, needs more
discussion/design.

Also some cleanup of postingAsLines.
