[PATCH v3 0/2] qemu-img: Make unallocated part of backing chain obvious in map

[Eric Blake <eblake@redhat.com>]

v2 was here [1]
in v3:
- pick up iotest change from [2] (rest of that series is abandoned)
- don't change semantics of "depth"
- make new witness unconditional, rather than optional
- spell new witness "present":true/false
