Cosmetics. :-)

I think it does:
backup  /var/                   dream/  exclude=/var/tmp

You can set cmd_preexec, cmd_postexec globally or per backup.

This should be possible with the latest rsnapshot (using sync/sync
first) and multiple incarnations of rsnapshot, but it's not in there
automatically.

rsnapshot does this now. :-)
