Here's the patches:

DISCLAIMER: Please note that whilst I've made every effort to test these
so far, I make no claim about their suitability.

That said, please test them in various invocations of 'subset' dumps
(i.e, dumping only certain files and directories in a mounted
filesystem), and see if what you can restore is what should have been
backed up.

Please get back to me via private email. If people are happy with
them, I'll post a followup in a few days, then commit it to the main
tree...
