My thinking was that it was useful for the disk format to have a bit
more information in it so that we could more easily change the interface
in an upwardly compatible way. If at some point in the future we do have
more general batch command processing, it would be nice not have to
change the file format again, particularly for dump files.

Well, as Jani mentioned there is a fair amount of code overlap with an
in-progress improved dump/restore facility.

Well, opinions seem to differ about how close we are to that in terms of
real code, but I think it is worth thinking about as we define file
formats.
