## Summary
Currently it's not backward compatible, because the flag -list-ignored doesn't
exists on older version of clang-format.
To make this tool still backward compatible, we can first check if the
.clang-format-ignore file exists before we run clang-format with the
-list-ignored flag.

Subject: [PATCH] Fix git-clang-format
Currently it's not backward compatible, because the flag -list-ignored doesn't
exists on older version of clang-format.
To make this tool still backward compatible, we can first check if the
.clang-format-ignore file exists before we run clang-format with the
-list-ignored flag.
