[JOE1994]

I've been using git clang-format without the --bin flag using the following setting

1. PATH=$PATH:~/llvm-project/build/bin:~/llvm-project/clang/tools/clang-format
2. Run git clang-format HEAD~1 at ~/llvm-project directory

After this revision, I get the following error:

error: cannot find executable "<FULL_PATH_UP_TO_LLVM_PROJECT>/llvm-project/clang-format"

(<FULL_PATH_UP_TO_LLVM_PROJECT> = full path to the parent directory of llvm-project directory)
