Thanks for noting that.

I don't think it will work, because it will face the same problem (the dump
doesn't store the deltas, only full files). Anyway I dumped the repository,
loaded to fresh new repository. Now the strings is 3MB bigger than in the
previous repository (113MB)...

So still the same question, how I can check the size of delta?
