Yes, this looks good.  I have tested it with my current version of gdb-mi.el
and it seems to work.  I will try to dig out the relevant patch for the
documentation and rework it, if Eli is also agreeable to this revision.

This gives:

(gdb)
-var-list-children
&"Variable object not found\n"
^error,msg="Variable object not found"
(gdb) 

instead of:

(gdb)
-var-list-children
&"mi_cmd_var_list_children: Usage: NAME.\n"
^error,msg="mi_cmd_var_list_children: Usage: NAME."
(gdb) 

I don't know if that's what you intended.
