Subject: fsck tests: test current hash/type mismatch behavior
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If fsck we move an object around between .git/objects/?? directories
to simulate a hash mismatch "git fsck" will currently hard die() in
object-file.c. This behavior will be fixed in subsequent commits, but
let's test for it as-is for now.
