Those scripts are bringing suffering on themselves by using porcelain instead of "git checkout-index". The usual way to look at a single file from the index is "git show :git.c >git.c".

So you've convinced me. I think --respect-skip-worktree can be just the normal behavior (and that there's no need for a --no-respect option). That would let me do:

	git clone --no-checkout git://repo.or.cz/git.git
	cd git
	echo '/Documentation/' >.git/info/sparse-checkout
	git config core.sparsecheckout true
	git checkout

	printf '%s\n' /README /INSTALL /COPYING >>.git/info/sparse-checkout
	git checkout

	... hack hack hack ...

	# return to what the index has
	git checkout .

without having to see any pesky actual source (*.c) files.
