| Add some headers:

| # xfs_db -c "freesp -d" /dev/sdb1
|     agno    agbno      len
|        0        4        1

|        0       12   174772
| ...
| 
| so there's at least some context.

The format is consistent with the "dumpflag" format in addtohist().  I
like your choice of strings, except I suggest "length" in place of
"len".  The space is available.
