rsync - Dec 2015 - strange behaviour when using (conflicting) options -q --progress

-q seems to override -v completely, but when combined with --progress,
a single newline is output when there are no updates transferred; but if
a file *was* updated nothing at all is output.

It seems that there might be some short-circuited code when nothing is
trasferred, but that a check for quiet mode is skipped somehow.

The bug report in Debian below may be related:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=749165
Here the issue is basically that a newline is *missing* after --progress
output has been generated. The output basically is:

 0 files...^M 400 files...^M 2500 files...^M 4600 files...^Ma1/
a2/

The a1/ part overwrites the " 4600 files..." part partially.

perhaps the extraneous newline in my first part is related to this
missing newline here?
