INITIAL arg to completing-read

[Richard S. <rm...@gn...>]

I changed the Lisp manual and doc string of completing-read
to deprecate use of the INITIAL argument.  This is an intrusive
interface, and now that we have history lists, we should in general
use them instead.

I also changed c-set-style not to use this feature any more.
Instead, it uses an ordinary default.  Here is the patch I installed.
