Subject: (ledger-reconcile): If a prefix argument is passed to C-c C-r
 (ledger-reconcile), then it will attempt to use the auto-reconciler to
 pre-mark the uncleared transactions.  Note that if it fails, and the
 uncleared list is long, it might appear to hang.  It's far from fool-proof,
 but when it does work, it's like magic!
