Merge "complete nudity" with "nudity"

There’s no functional difference between the “complete nudity” tag and the “nudity” tag.

There is supposed to be. For example, if you have a picture where one character is only topless and another is completely nude, “topless” involves “partial nudity” (and “nudity”) but that doesn’t identify that there is also a completely nude character present.

Nude characters here can still be mostly clothed. Completely nude characters should not be.

Well said.

Rather than merging them, complete nudity should imply nudity, as has already been suggested here

Added the implication
