Public bug reported:
If you upload a large file into swift using "swift -S" (or presumably
the upload() method) then add extra metadata using "swift post -m" (or
post_object()), the large file manifest metadata is deleted. It
shouldn't do that.
$ swift upload -S 10000000 chrisstest /boot/initrd.img-3.16.0-22-generic
boot/initrd.img-3.16.0-22-generic segment 3
boot/initrd.img-3.16.0-22-generic segment 0
boot/initrd.img-3.16.0-22-generic segment 1

Interestingly, "swift download" (and the get_object() method) do re-
create the segmented file correctly even without the manifest (does it
just make an opportunistic look for chrisstest_segments?)
