I stand corrected. It is there. But still: this is a general behaviour
of rsync that is independent of most command line options. And yet, "the
temporary file" is just an unexplained term that appears in the middle
of the description of a (rarely used) option, and the "renamed only
after the transfer has completed" part is completely missing. That said,
it is just an excuse on my side. I should have figured it out. :-)
