deprecate +_-
Another Oldbooru relic.
This time it's the tag "+_-", which originally seems to be used for characters with a literal plus - minus eye pupils (example; post #402676), but it was often used for when a character with starry eyes (tagged as "+_+") have one of their eye closed (example; post #4536897), or when the plus - minus symbol appeared together (like this Plusle & Minun post #7178831).
Given that it's literally used for only few OC characters, and that people are now used this usually for when starry-eyed character wink (which can be easily searched with +_+ + one_eye_closed), I don't think this tag serve any purposes other than causing confusion, and therefore it should be deprecated.
