Whoever most recently updated the _arguments call in _rsync asserted that
-P and --progress are mutually exclusive.  That's intended to prevent the
--progress option from being offered again if you already used -P, I'm
sure, but it also means that the comparguments builtin treats them as
truly mutually exclusive, i.e., the command is wrong if both appear.

Currently _rsync also excludes -P when either of --progress or --partial
already appears, which is probably a mistake.

Ideally comparguments would have a variant of "mutually exclusive" that
simply means "redundant".  In the meantime you could locally apply
this patch:
