`packedRefUnsorted`::
	(ERROR) The "packed-refs" file is not sorted.

`refMissingNewline`::
	(INFO) A loose ref that does not end with newline(LF). As

	file, it may become an error in the future. Report to the
	git@vger.kernel.org mailing list if you see this error, as

`symlinkRef`::

	creating symbolic links as symrefs.

	the rule in the future. Report to the git@vger.kernel.org
	mailing list if you see this error, as we need to know what tools
	created such a file.

`trailingRefContent`::
	(INFO) A loose ref has trailing content. As valid implementations
	of Git never created such a loose ref file, it may become an
	error in the future. Report to the git@vger.kernel.org mailing

	created such a file.
