Yeah, I agree you and Ævar that the topic may be over-engineering
the solution for problem that we shouldn't be the ones who solve.

I agree with your analysis that the "diff" tempfiles do need suffix,
we SHOULD create them in $TMPDIR (not in the working tree or
$GIT_DIR) to support operation in a read-only repository, but we can
create a unique temporary directory and place a file (even under its
original name) in it as a workaround.

Thanks.
