125 return if ( !$p->getoptions($rs->{rsyncOpts},

Note that whole-file is not included in the list of options that it looks for,
so it is ignored by RsyncP. This is 0.68 but it is the same deal in 0.70.

Where are you finding that in the RsyncP code? I see it always does
whole-file when sending (restores) but don't see anything about not passing it
to the other side for backups (but didn't look much beyond a grep for
'whole'...).
