1. an emerge command seems to be structured like emerge [options] [action] [targets] but the targets are described in the section actions. this confuses as the structure and the indentation of their explanations and the following description of actions look identical and the point where description of targets end and description of actions begin is not obvious. 2. reading the mapage, I would expect emerge --clean rsync and emerge -c rsync to behave identical. but with -c it behaves like emerge clean rsync which is not mentioned at all.
This is resolved in 2.0.18+
