[PATCH] fix some documentation menus

[Bob Wilson <bwilson@tensilica.com>]

[-- Attachment #1: Type: text/plain, Size: 609 bytes --]

This patch fixes some out-of-order menu entries and removes some menus that 
don't match the hierarchical structure of the document.

It also removes some unnecessary next/prev/up arguments from a @node entry, 
since they can cause problems for conditional text and since none of the other 
nodes (except Top) specify those arguments.

OK?

2007-03-23  Bob Wilson  <bob.wilson@acm.org>

	* gdb.texinfo (Top): Move TUI and Annotations menu entries to match
	the order of the nodes.
	(C Operators, C Constants, Debugging C): Remove extra menus.
	(Method Names in Commands): Do not specify next/prev/up nodes.
