Hi, all...

The set command for "var_enum" type gdb variables will give you a 
helpful error message if you say something like:

(gdb) set osabi
Requires an argument. Valid arguments are auto, default, none, Darwin, 
Darwin64.

But not if you do:

(gdb) set osabi Blubby
Undefined item: "Blubby"

It would be nice if folks didn't have to remember that osabi is an enum 
type variable, and they should go back and type "set osabi" with no 
arguments, etc.  The following patch makes it symmetrical, so you get:

(top-gdb) set osabi
Requires an argument. Valid values are auto, default, none, Darwin, 
Darwin64.
(top-gdb) set osabi foobar
Undefined item: "foobar". Valid values are auto, default, none, Darwin, 
Darwin64.
(top-gdb) set osabi Darw
Ambiguous item "Darw". Valid values are auto, default, none, Darwin, 
Darwin64.

Does this seem good?

variables,
	return the list of valid values for all errors, not just no argument.
