We discussed this kind of properties some time ago. We could use them
for other features too. So yes, I'm in favour of properties too.

This has nothing to do with the db backend. It has to do how revisions
are stored in the currently used backend. It only stores immediate
copies. So for example, if you create a copy (tag) from trunk@100, you
don't get that information by showing the log of /trunk/file. Because
the copy information is only stored for "trunk", not its children.

That's also the reason why the revision graph has to fetch the log from
the repository root - we couldn't get the information when e.g. a tag is
created from a branch because we don't get that information by showing
the log of trunk.

See issue #45:

But I know this would be a nice feature. I have to study the subversion
code a little bit more. Maybe I can find an easier way to accomplish
that, but maybe it's just not possible without showing log for
repository root - we'll see...
