Thanks.  Oddly enough, pruning of old backups hasn't been a really
high priority for me (or apparently any of the other users) because
chunking-based deduplication is so efficient that my backup disk
hasn't filled up yet :)  But it's clear that this will need to be
added eventually.

Unfortunately git's normal pruning and gc stuff is inapplicable since
it dies horribly when faced with hundreds of gigabytes of data.
That's to be expected, but it means I can't just cheat by running 'git
gc' and hoping for magic.

Have fun,
