    manual: Refactor documentation of CHAR_BIT.
    
    This single-@item @table is better defined with @deftypevr, since the
    CHAR_BIT macro has @standards (being declared in a header), and @items
    in @tables are not considered annotatable.  Using @deftypevr
    automatically includes the macro in the Variable and Constant Macro
    Index and ensures its inclusion the Summary of Library Facilities.
    @deftypevr is used to record the type of the macro so that it also
    appears in the Summary.
    
    The description is updated to mention a later POSIX requirement that
    this macro have the value 8.
    
    	* manual/lang.texi (CHAR_BIT): Convert from an @table to an
    	@deftypevr.  Change standard from ISO to C90.  Mention the
    	POSIX.1-2001 requirement of the value 8.
