clang-format-diff exits after parsing the first file of the input diff

[Gaël Bonithon]

Hi, the python script clang-format-diff of the package clang-format has a bug, it displays only a part of its diff, it needs this patch: https://github.com/llvm/llvm-project/commit/d9e3e11ae57612ec61f6fcab4afc27d8d0ff5841
At Xfce, we've recently been using clang-format-diff in CI [1], with Ubuntu 24.04 and therefore clang-format-18, which is affected by this bug.
Is there any hope that clang-format-18 will be patched in Debian and/or Ubuntu to integrate this patch, or should we upload the latest version of clang-format-diff in our container? Thanks!
