You don't say exactly what you want to achieve so I can't tell you
exactly what you need. In your subject you talk about changesets, but it
seems that you are concerned about diff updates published on
openstreetmap.org. If that'S the case: They are not cumulative; you have
to find out what the timestamp of your data set is and download those
between then and now.

Osmosis' "read-replication-interval" action can help you keep track of
how current your data is, and download all changesets between then and
now, and combine them into one automatically.

Yes, *and* multiple --apply-change of course. But if you use
"read-replication-interval" then you will only deal with one diff file
that has all the changes.
