Of course on newer git, `git-rev-parse $commit:` will do that.

Are you sure? Maybe you mean git-rev-parse "$commit"^{tree}?

I had the same "Huh?"  moment as you had, but what Sam said is
correct.  He is being too clever to confuse us ;-).

When "$commit" is a tree-ish,

	$commit:$path

is the name of the tree or blob object at that $path, and as 
very strange special case, an empty $path is the whole tree.

It's been this way since early this year (before v1.5.0-rc1),
thanks to Jeff King.
