Ah, yes, that. I've been wondering about that myself, and it seems wrong
to record an add and delete if we're not, in fact, doing that. I'd
rather introduce rename-source and rename-target records; the -source
should somehow contain the target path, and the -target should contain
the source path, so that we can follow the rename in both directions.

Ahh, we do need to store a rename flag after all :) So where would the
extra path go? In a new renames table? In the existing changes

I've just taken another look at the structure. I think we can record
this in the changes table, and we can glean the source and target paths
of the renames with the help of the txn-id stored in the change record.
We can even smell out the rename+modify thing, by noticing that we got a
rename-target and a later modify record on the same path in the txn.
