mass update hashtag-only_commentary commentary -> -commentary
For years, even before hashtag-only_commentary was a tag, the consensus had been that "commentaries that have only hashtags shouldn't be tagged with commentary". Yet, as of writing this topic, roughly third of the posts are tagged with such. Alternatively, if people want these to be tagged with commentary, it would be better to implicate it.
