Tabular reports from bal, bs etc. have until now been rendered on
the terminal with one final blank line, for readability.
This change drops the blank line.
This is consistent with the non-tabular balance and register output
(not print, which is a special case), and with most unix commands.
The real reason for it, which I admit is flimsy, is that I can now omit
the final delimiter (>=0) when using shelltestrunner 1.9's new format,
making functional tests easier to maintain and more readable.
If there's opposition, this could be reverted.
Previously, if you specified no report interval, the text output of
these commands was a simple report like the original balance command,
with amounts on the left and account names on the right. Also,
balances used arithmetic sign like the balance command.
Now it always draws a table, with account names in the left
column, and shows balances with normal-positive sign, consistent with
the multicolumn reports. Less code, fewer bugs.
For multi-column balance report, if there are no transactions in the
given period for budgeted account, display [0% of <budget>] for
consistency.
If balance is a mix of commodities, convert to cost basis for the
purposes of computing percent of balance spent.
Budget goals specified with periodic transactions (as with
hledger-budget) can now be displayed in balance report (but not in bs/is/cf).
--budget shows the target amount and percentage alongside the actual
amount, per account and period.
Unbudgeted accounts will be hidden, unless --show-unbudgeted is used.
Budgeted accounts are displayed folded (depth-clipped) at a depth
matching the budget specification. Unbudgeted accounts, if shown, are
displayed at their usual depth (in full detail, or according to --depth).
