Oops, I forgot to mention the actual solution. :)

Generally it is safe to clone _from_ an untrusted repo, even if it's on
a local filesystem. So untarring the repo and running:

  git clone evil.git safe
  cd safe
  git log

should make it OK to run Git commands inside the "safe" directory.

Jonathan Nieder also mentioned using a bundle file, which may be even
simpler, as it skips the part where you have to deal with tar. :)

Run:

  git bundle create foo.bundle --all

on the sending side, and then you can just:

  git clone foo.bundle safe

on the receiving side.
