After running python beangrow/configure.py -v simple.beancount > conf-simple we get following conf-simple (everything is as expected)

investments {
  investment {
    currency: "AAA"
    asset_account: "Assets:Investments:AAA"
    cash_accounts: "Assets:Investments:Cash"
  }
  investment {
    currency: "BBB"
    asset_account: "Assets:Investments:BBB"
    cash_accounts: "Assets:Investments:Cash"
  }
}
groups {
  group {
    name: "currency.AAA"
    investment: "Assets:Investments:AAA"
  }
  group {
    name: "currency.BBB"
    investment: "Assets:Investments:BBB"
  }
}

But if we close account AAA (after we sold investment)

2019-07-01 price BBB                        300 USD

after running python beangrow/configure.py -v simple.beancount > conf-simple we get following conf-simple (account AAA is ignored)

Using the --start-date option to configure.py works correctly. However, the default behavior, when that option is not used is unintuitive IMHO. Possible solutions:

• use an arbitrary default of say, 15 years for the start date (still trips up users)
• Assume start date is the beginning of time, unless otherwise configured
