When we are initializing a .git directory, we may call probe_utf8_pathname_composition to detect utf8 mangling. We pass in a path buffer for it to use, and it blindly strcpy()s into it, not knowing whether the buffer is large enough to hold the result or not. In practice this isn't a big deal, because the buffer we pass in already contains "$GIT_DIR/config", and we append only a few extra bytes to it. But we can easily do the right thing just by calling git_path_buf ourselves. Technically this results in a different pathname (before we appended our utf8 characters to the "config" path, and now they get their own files in $GIT_DIR), but that should not matter for our purposes.
