[PATCH 06/24] Fix "set enum-command value garbage"

[Pedro Alves]

With enum commands, we currently fail to notice garbage after the
value.

Currently:

  (gdb) set print entry-values compact foo
  (gdb) show print entry-values foo
  Printing of function arguments at function entry is "compact".

After this fix:

 (gdb) set print entry-values compact foo
  Garbage after item: "foo"

	* cli/cli-setshow.c (do_set_command) <var_enum>: Detect garbage
	after item.
