You misinterpreted what i said. I said revision data, not revision
properties :)
*Revision* properties (not the same as versioned properties on files
or directories) are not checksummed.

The revision properties basically consist of the log entry, author of
revision, etc.
Things that are tied to exactly one revision.

We don't bother to checksum them, because they are unversioned, and
you shouldn't be storing anything critical in there anyway.
