Balance tab does not handle virtual postings well

[JesseFL]

Ledgerble is not displaying virtual postings well. The below example is duplicating the account Budget:A because there are 2 entries to this account, one in each style of virtual posting.

4/9         Paycheck
    Assets:Checking                    $100.00
    Income:Boss
    [Equity:Budget]                     $-100
    [Budget:A]                          $70
    [Budget:Z]                          $30

4/12        Groceries
    Assets:Checking                   $-10.00
    Expenses:Groceries
    (Budget:A)                        $-10

Additionally, the display of these accounts contains erroneous brackets () and []. The virtual postings should reflect on the balance just as if they were a real posting.
