[PATCH 0/1] Properly peel tags in can_all_from_reach_with_flags()

As Peff reported [1], the refactored can_all_from_reach_with_flags() method
does not properly peel tags. Since the helper method can_all_from_reach()
and code in t/helper/test-reach.c all peel tags before getting to this
method, it is not super-simple to create a test that demonstrates this.

I modified t/helper/test-reach.c to allow calling
can_all_from_reach_with_flags() directly, and added a test in
t6600-test-reach.sh that demonstrates the segfault without the fix. The fix
in commit-reach.c is Peff's fix verbatim.
