GDB/MI Compatibility with CLI

To help users familiar with GDB's existing CLI interface, GDB/MI
accepts existing CLI commands.  As specified by the syntax, such
commands can be directly entered into the GDB/MI interface and GDB will
respond.
   This mechanism is provided as an aid to developers of GDB/MI clients
and not as a reliable interface into the CLI.  Since the command is
being interpreteted in an environment that assumes GDB/MI behaviour,
the exact output of such commands is likely to end up being an
un-supported hybrid of GDB/MI and CLI output.
