[PATCH v2 0/2] Lazy fetch bug fix (and feature that reveals it)

I verified that 5616 is broken on [master + md/filter-trees + my patch],
and after investigation, found a bug in the lazy fetch implementation.
Patch 1 contains a fix, and more information about that bug.

Patch 2 is the original patch, updated with the commit message I
suggested [1] in reply to Junio's comment.

I bundled these patches together because patch 2 (in combination with
certain other commits) reveals the bug that patch 1 fixes, and to make
it easier for others to verify that these patches together pass all
tests when rebased on [master + md/filter-trees] or 'pu' (at least, as
of the time of writing).
