Recently in the edit cue, there have been edits that only add `<!-- language: bash -->` to the post. These edits are made by the same user. And often 5-10 at a time.

Is the color highlighting of code really a necessary edit? Presently I have been skipping them because I don't know if this should be considered an improvement.
