Looks good - similar specs are already used in other places.

BTW: I find the definition of `electric-indent-local-mode' inelegant:
the handling of the variable is split between the :variable spec and the
body.  The body enables the global mode and sets the global variable
back to nil - quite hackish.

Anyway, if this is needed in more places it cries for a
`define-localized-mode'.

Michael.
