Indeed. This seems to be a problem in the replay API.
This is not a problem for svnsync itself because svnsync manually
sets the revision properties while doing a sync.
We can fix the replay API to allow svnrdump to get revprops for r0.

OK.

We can fix this later.

Well, it would be really nice to have.
Details like this are time sinks, I know. But it pays off.
You don't have to do it right away. We can file an issue so we don't
forget about fixing it before 1.7 release.
If necessary, feel free to adjust the output of svnadmin dump a little
if that makes it easier for svnrdump to produce matching output.

Fine for testing. But I still think the end-result should look just
like svnadmin dump, if possible. That would make testing even easier.

What about using git until then? It does not matter which state you
initially import into the Subversion repository. But well, whatever
works for you is best.

Thanks, I'll take a look.
