Re: eliminate deprecated_add_set_cmd


Hi guys, I apologise for the delay in getting back to this.

The patch at the bottom is now checked in.  I've managed to bork
up my debian/Hurd VM (*), and I don't remember if I ever build this
patch on the Hurd. :-/  I apologise if this breaks anything, but it
should be trivial/obvious to fix if so.  :-)

How's this?

	* NEWS: Mention that the `maint show-debug-registers' and
	`gnu-debug' commands were renamed to `maint set
	show-debug-registers' and `set debug gnu-nat' respectivelly.

This is what I've already applied:

2009-05-12  Pedro Alves  <pedro@codesourcery.com>

	* cli/cli-decode.c (deprecated_add_set_cmd): Delete.
	* command.h (deprecated_add_set_cmd): Delete declaration.
	* gnu-nat.c (_initialize_gnu_nat): Replace 'maint gnu-debug' with
	'set debug gnu-nat' and 'show debug gnu-nat'.
	* i386-nat.c (_initialize_i386_nat): Replace 'maint
	show-debug-registers' with 'maint set show-debug-registers' and
	'maint show show-debug-registers'.
	* mips-linux-nat.c (_initialize_mips_linux_nat): Replace 'maint
	show-debug-registers' with 'maint set show-debug-registers' and
	'maint show show-debug-registers'.

2009-05-12  Pedro Alves  <pedro@codesourcery.com>

	* gdb.texinfo: Document 'set/show debug gnu-nat'.  Replace 'maint
	show-debug-regs' docs by 'maint set show-debug-regs' and 'maint
	show show-debug-regs' docs.
