[JGIT PATCH] Paper bag fix IndexPack thin pack completion support

We must write the whole object at the end of the file, not in the
middle of the file on top of some delta (or other) whole object.
Writing in the middle of the file causes subtle corruption as we
cannot unpack a delta.

 This is a serious data corruption in IndexPack.  It was introduced
 by me in "Compute packed object entry CRC32 data during IndexPack",
 which is presently in `pu` as 4b8e1c0c.  It would be best if we
 squash this into the commit.
