Surely a program cannot cover everything and the user has to go
through the changes and fix some stuff manually.  Or there should be a
"Enter recursive Edit" functionality as in `checkdoc'.

It cannot figure out the :type for all defvars, but I think 80% could
be guessed heuristically (e.g. if value is t or nil, take 'boolean).
The custom :group could be asked once per buffer.

Bye, Reiner.
