Thanks Doug for the update.

In 6.4.2:
"keep the last T minutes worth of data, at most N versions, *but keep at
least M versions around*" (where M is the value for minimum number of row
versions, M<=N)

Please refer to discussion toward the end of HBASE-4536 where Lars suggested
dropping support for the case of M==N > 0.

Cheers
