True. Though I don't expect a huge speedup. I guess for 'commit' it
would be a bit faster, because we would only have 1 serialize call,
rather than 2.

However, dirstate doesn't have a basis-inventory-cache. So we might as
well just switch over.

Looking at the code, it seems 0.8-0.10 use format 5, and then 0.11-0.14
use format 6.

I guess I would rather use format 6 for 0.15, since WT3 is otherwise
unaltered from earlier formats.

Don't worry about it. I found the problem. I just had an older branch
that didn't have that fix. I just merged the latest bzr.dev and I got it.

Sorry for the noise.
