docs: Parses a statement containing one or more keyword definition(s) and/or value assignments, like `name1 name2= name3="" name4=value`. Note that this is a stricter format than the old format of assignment, allowed by parseNameVal(), in a way that this only allows assignment of the form `keyword=[<value>]` like  `name2=`, `name3=""`, and `name4=value` above. In addition, a keyword definition alone is of the form `keyword` like `name1` above. And the assignments `name2=` and `name3=""` are equivalent and assign an empty value to the respective keywords.
