Then we have to figure out why that happens. vdelta definitely won't be
very god at compressing differences between binary file types that are
already compressed -- that includes ZIP file, JAR files and many image
types (GIF, PNG, JPEG come to mind, TIFF can be LZW compressed, etc.).
It's possible that, for these kinds of files, we should always store the
fulltext.
