Re: bug? `define-derived-mode' doesn't set `derived-mode-parent' property

Nor does anything set it. If GNU doesn't have it, we should consider
getting rid of it entirely. It's easily implemented as a function.
`dired-mode', `eshell-mode', `ibuffer-mode' (yay!), etc. have a
mode-class property. If I used `define-derived-mode' to make my own
`froody-dired-mode' then it'll copy the mode-class property for free.
Also, `completion-list-mode' depends on this.
