Subject: restart: fixes for 32bit and chunked items.

severe bug in item chunk fixup (wasn't doing it at all!)

failed to check on my 32bit builders... and 32bit platforms weren't
working at all. This is a bit of a kludge since I'm still working
around having ptrdiff, but it seems to work.

also fixes a bug with missing null byte for meta filename.
