Inconsistent flags of thin volumes and snapshots

Inconsistent flags of thin volumes and snapshots

[ben]

I have noticed inconsistencies in the flags with regard to
thin volumes. I haven't posted them as bugs yet though because I
am not sure if some are intentional.

The first column of the flags is 'o' when a normal snapshot is taken
of a thin volume but is 'V' when a thin snap is used. I haven't
checked to see if 'O' is used for merging with thin snapshots.

The other issue I have run into is that a thin snapshot doesn't
put an 's' into column 1 or column 7. This makes parsing more
difficult since a thin volume and thin snap look the same in the
flags. It seems that one of the columns could be changed to
an 's' without losing any information. The first column also is
used for merging 'S' so that would probably be the best one.

Should I post these as bugs?

Thank you.
