+ clipboard register '+' (|quoteplus|) instead of
+ register '*' for all yank, delete, change and put
+ operations which would normally go to the unnamed
+ register. When "unnamed" is also included to the
+ option, yank operations (but not delete, change or
+ put) will additionally copy the text into register
+ '*'.
