        <pre>On windows, the mode parameter to openNativeFile is not used. Instead, the
implementation of openNativeFile calls the win32 function CreateFileW to create
the file. It passes CreateFileW a SECURITY_ATTRIBUTES object with its
lpSecurityDescriptor field set to nullptr. This results in a file with the
default permissions.

The symptom of all of this on my machine is that clang-format -i changes the
source permissions to have the executable bit set.</pre>
