	* command.h (enum command_class): New class 'no_set_class', for
	"show" commands without a corresponding "set" command.
	* value.c (_initialize_values): Use 'no_set_class' for "show values".
	* copying.c (_initialize_copying): Ditto for "show copying" and
	"show warranty".
	* cli/cli-cmds.c (init_cli_cmds): Ditto for "show commands" and
	"show version".
	* cli/cli-setshow.c (cmd_show_list): Skip "show" commands for
	which there is no corresponding "set" command (eg. "show copying").

2011-02-14  Michael Snyder  <msnyder@vmware.com>

	* gdb.texinfo (threads): Document argument for "info threads" cmd.
	Document new command "thread find".

2011-02-15  Michael Snyder  <msnyder@vmware.com>

	* gdb.base/default.exp: Add tests for thread commands.
	* gdb.base/help.exp: Add tests for thread commands.
	* gdb.threads/thread-find.exp: New test for thread find command.
