- Now the full wake history uses the history tag if it can.
Hopefully this will still result in a consistent history,
since that isn't really want the tag is for... but the
current implementation in places will probably make this work.
- Possibly fix a bug with inconsistent state between partial
history snapshots: after a snapshot is printed, don't allow
any more batching into the most recent history entry, so the
next snapshot will not miss anything that might get placed
into it soon after.
Also rework command line arguments for enable/disable to make these
commands instead of options.
