The --dry-run option disables actually doing the transfers.  You would
use it in combination with whatever output options you like (-v, -i,
--out-format, etc.).

That is not currently implemented.  One way this could work is to use
--delay-updates --delete-after and prompt the user just before the
delayed update/delete pass.  If the user cancels, staged files will be
left in .~tmp~ directories in the destination, but these can easily be
deleted by a shell script.
