Everything is working beautifully.  I've changed the backup program to
handle a new dumplist format, where a dump schedule is given by level up
dump requested, rather than just I or F.  I am currently ironing out the
details of how "ancient" information is stored, and exactly what happens
when a dump of a particular level is requested.

Once this is taken care of (which it should be before too long), I will
change merge to allow the merging of an incremental dump onto another of
strictly lower level.
