In a nutshell:
prints out one line per transferred file. The last line (auto updated) is the currently transferred file.
It seems to somehow loose the transferred history and display the header (very informative and somehow reports Transferred: which is already something) and the current transfer only.
I was wondering if there a way to run rclone -P in a rsync -P way. This might occasionally turn out to be very helpful.
P.S. I know I can log the transfer but my question is revolving about console output.
