On the subject of where the check gets added, the old description said

	It's easier to handle than .gitmodules, because we don't care
	about checking the blob content. This is really just about
	whether the name and mode for the tree entry are valid.

which I think was self-explanatory enough.  The new text is a little
more confusing because I get lost in figuring out what the "it" in
"Its" refers to.
