The thing is, when you're in picture mode, you're *not* in C mode,
perl mode, or whatever mode you really want to be in.  He just wants a
few features of picture mode to be on all the time.  Something like:

(require 'picture)
(global-set-key (kbd "<right>") 'picture-forward-column)
(global-set-key (kbd "<up>") 'picture-move-up)
(global-set-key (kbd "<down>") 'picture-move-down)
(add-hook 'before-save-hook 'delete-trailing-whitespace)
