Re: [RFC PATCH 3/7] t3705: add tests for `git add` in sparse checkouts

Then, the test would become:

	setup_sparse_entry &&
	test-tool cached_mtime sparse_entry >before &&
	test-tool chmtime -60 sparse_entry &&
	git add --refresh sparse_entry &&
	test-tool cached_mtime sparse_entry >after &&
	test_cmp before after

What do you think?

I do not see much point in introducing a duplicated "ls-files --debug"
that gives only a subset of its output.  Even if we add test-tool,
we would need to reserve the right to change its output format any time,
so I am not sure what we'd be gaining by avoiding the use of
existing one.

Thanks.
