OK.  I've committed the -stack-info-frame part of the change that posted (Sat,
18 Jun 2005 10:52:09 +1200).  Perhaps that doesn't follow the letter of the
law but I hope it follows the spirit.  In any case, I find it easier to make
further changes to the repository than juggle patches (as demonstrated shown
with my earlier mangling).

This commit is slightly different in two respects:

1) mi_cmd_stack_info_frame uses print_frame_info instead of print_stack_frame.
   This follows mi_cmd_stack_list_frames and means that the argument values
   aren't printed.

2) The documentation for -stack-info-frame previously said (before I removed
   it) "Get info on the current frame.".  I've corrected this to
   "Get info on the selected frame."  I've also removed the argument values
   from the example as explained in 1).

I hope this is acceptable.

	* mi/mi-cmd-stack.c (mi_cmd_stack_info_frame): New function.

	* mi/mi-cmds.c (mi_cmds): Replace entry for -stack-info-frame.
	Make it use mi_cmd_stack_info_frame

	* mi/mi-cmds.h (mi_cmd_stack_info_frame): New declaration.

	* gdb.texinfo (GDB/MI Stack Manipulation):
	Re-instate -stack-info-frame with example.  Say that it gets
	info on selected frame, not current frame.
