Okay --- here's what I've committed.

2005-11-16  Jim Blandy  <jimb@redhat.com>

	* gdb.texinfo (Packets, Stop Reply Packets)
	(General Query Packets): Various formatting cleanups.
	- Use @samp for packet contents.
	- Drop summaries from packet @item lines; the same information appears
	  immediately below in the description.
	- Delete paragraph breaks after packet @item commands, so that the
	  description appears directly to the right of the packet prototype
	  in the printed manual, if it fits.
	- Place spaces in packet prototypes between @vars and non-@var
	  letters, and explain that they're just for formatting.
	- Use @dots{} instead of '...'.
	- Fix uses of @code where @var was needed.
	- Replace "deprecated" markers with English text spelling out the
	  packet's status and the preferred alternatives.
	- Remove "(reserved)" markers on 'A' and 'I' packets; it's unclear
	  what this ever meant.
	- Remove "(draft)" markers on 'i' packets; nobody has commented on
	  this for a long time.
	- Remove "(draft)" markers on 'z' and 'Z' packets; these have been
	  implemented several times, and have been in use for years.
