So, rather than use "listed-incremental" to recognize
it is a renamed directory, gnutar's behavior is to
consider then entire directory tree "changed" and
back up the entire tree.

Reading this thread reminded me of another one where
the poster was complaining about this "feature" of
gnutar.  That poster has a lot of rotating log dirs
that were quite large.  They were rotated by renaming
them each night (log.2 becomes log.3, log.1 -> log.2 etc.)
Their complaint was that the data in the directory WAS
being backed up each night though it was unchanging.

Be nice if gnutar could deal with both needs.
