Hmm. I don't know what the difference might be. debian-unstable is
usually not *so* ancient that I'd expect big git version differences
(even if I personally tend to run very recent git trees, because it's
the one thing in addition to the kernel that I build myself).

Sometimes things like the git rename limits hit people. Your side
didn't have a lot of file creation/deletion (which is when the default
git rename limits can bite you), but my side did.

Did you perhaps also get a message like "inexact rename detection was
skipped due to too many files"? If you have lots of memory, it can be
a good idea to just disable the rename limits:

  git config diff.renameLimit 0
  git config merge.renameLimit 0

but it's also possible that some tweak to the diff algorithm triggered
this, or just the fact that we tried merging at slightly different
points.

Not a big deal.
