This is because nil will just call `kill-all-local-variables',
and if you specify, special-mode it will call `kill-all-local-variables'
for you.

Theoretically you can do this by setting PARENT to `ignore', but I
wouldn't advise doing this.  Feels wrong...  The other solution would be
to use dynamic variables and bind them before calling `mpdired-mode'.
