Log message:
	* cpphash.h: ISvspace, is_vspace, is_nvspace: New.
	IShspace, ISspace: Update.
	
	* cppinit.c: ISTABLE: Update.
	V: New.
	
	* cpplex.c (IS_HSPACE, S_NEWLINE): Remove.
	(IS_DIRECTIVE): Rename KNOWN_DIRECTIVE.
	(skip_block_comment, skip_line_comment,	parse_string,
	lex_line): Use is_vspace rather than IS_NEWLINE.
	(skip_whitespace, lex_line): Clean up to use is_nvspace.

	gets a BOL flag.

	Treat directives within macro invocations as directives
	(after parse_args emits error), not as the argument.
