Note the deviation of "mb" in the watchlist versus "m" everywhere else.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
I currently can't tell if a bot operator has the bot flag enabled or not unless the edit in question shows up on my watchlist. When I checked https://en.wikipedia.org/wiki/Wikipedia:Bots/Requests_for_approval/TolBot_11 it appeared as if the edits were only marked as minor, not bot. Then I checked some edits I know to be marked as bot edits and outside my watchlist couldn't tell if they were marked as bot edits either.

Benefits (why should this be implemented?):
Obvious innit? I had to add a page edited by TolBot to my watchlist just to verify that it is indeed marked as a bot edit. That's cumbersome.
