I fixed a bug. Turns out "delete comment" didn't work, for some unspecified amount of time, but probably since early this year. It failed in a very obvious way though, so I doubt anyone was misled into thinking they had removed a comment. All tidied up, sorry about that. Thanks to the person who reported it.

I also modernized a few boring technical details while I was in the neighborhood.

Every now and then I remember my new machine has a touchscreen. Then I try to forget. I'll never clean it.
