A simple single-column balance report. It has:

1. a list of rows, each containing a renderable account name and a corresponding amount
2. the final total of the amounts

A renderable account name includes some additional hints for rendering accounts in a balance report. It has:

• The full account name
• The ledger-style short elided account name (the leaf name, prefixed by any boring parents immediately above)
• The number of indentation steps to use when rendering a ledger-style account tree (normally the 0-based depth of this account excluding boring parents, or 0 with --flat).

Enabling this makes balance --flat --empty also show parent accounts without postings, in addition to those with postings and a zero balance. Disabling it shows only the latter. No longer supported, but leave this here for a bit. flatShowsPostinglessAccounts = True

Generate a simple balance report, containing the matched accounts and their balances (change of balance) during the specified period. This is like periodBalanceReport with a single column (but more mature, eg this can do hierarchical display).

When true (the default), this makes balance --flat reports and their implementation clearer. Single/multi-col balance reports currently aren't all correct if this is false.
