Re: Getting more info on a variable in Customize buffers

[Richard Stallman]

    Actually, I doubt it's even useful because buffer-local customizations can't
    be usefully saved in a .emacs.  What I'd rather want (as a user) is 
mode-local
    customizations.

I think that buffer-local customizations are somewhat useful even if
they cannot usefully be saved.  (And maybe they can be saved, if you
use desktop.)

However, mode-local customizations are a good idea for a future feature.
