As I mentioned in a separate thread (for the log template stuff),
using the cached property value until the next update is a valid
design/mode of operation and would be consistent with how the rest
of the WC stuff works today.

IOW, "svn diff" doesn't need to check the validity of the cache, it
can depend on "svn update" to do the work for it.
