Multicolumn balance reports can now be switched to a hierarchical view with --tree. This is similar to the single column balance report with --no-elide, ie we do not elide boring parents into the following line. The --flat and --tree flags are opposites; the last one to appear on the command line is decisive (in future, if not already).
