[lvm-devel] [PATCH] Fix dmsetup table output (different format in 2.02.85)

[Milan Broz]

In previous versions < 2.02.85 dmsetup table <dev>
produced just dmsetup table, no device.

# dmsetup table abc
0 100 zero

Now is the output changed to:
# dmsetup table abc
abc: 0 100 zero

It should be only for all and multiple devices, not for one.

It breaks at least cryptsetup test suite, I guess there
are more problems.

Patch somehow workarounds it, I have no idea what was the intention
for this change.
I guess even Alasdair should use patch review process sometimes :-p
