Obj-C seems to have only 2 specific warnings (which are not generic).
-Wall is not mentionned there at all, and I have no clue if these warnings are
enabled by it or not.  An Obj-C maintainer should probably clarify this.

For C++ it seems OK.

So here is my new proposal :

	* doc/invoke.texi (-Wreorder): Remove remaining pieces from the generic
	section.
	(-Wall): Mention that there can be language-specific warnings as well.
