Agreed.

Here's another problem:

     C-x 5 2             ;; make-frame-command
     ;; handle-switch-frame
     <help-echo> <help-echo> ;; handle-switch-frame
     ;; handle-switch-frame
     ;; handle-switch-frame
     ;; handle-switch-frame
     ;; handle-switch-frame
     ;; handle-switch-frame
     ;; handle-switch-frame
     C-                 ; ;; nil
     ; ;; self-insert-command
     C-h l ;; view-lossage

I'm not sure why there's no `switch-frame` event but it absence leads to
incorrectly indenting the `;; handle-switch-frame`.

We're probably better off indenting "by hand".
