Intra-diff for reference.  It mostly shows that the tweaks you made got
git a bit confused; since 'git diff --patience' shows a smaller diffstat of:
 qapi-schema.json     | 1406
--------------------------------------------------
 qapi/block-core.json | 1406
++++++++++++++++++++++++++++++++++++++++++++++++++
 2 files changed, 1406 insertions(+), 1406 deletions(-)

and therefore your larger stat on qapi-schema.json was due to 'git diff'
picking some lines as deletions and reinsertions instead of context to a
larger chunk of moved text.  Since I was able to apply the patch and run
the patience algorithm, I'm confident your code motion was clean.
