  JB> How does rdiff-backup treat such files?

Sorry, rdiff-backup is too dumb to know that a file has moved.  To
rdiff-backup, moving file A to B is equivalent to creating a new file
B and deleting A, so increments will contain duplicate information.
There have been some proposals about tracking renames through inode
numbers or similar file names, but they are pretty complicated and I
don't intend to implement them.

That being said, log files compress well, so you may want to try it
anyway in case the duplication is tolerable.
