commit 3cd89a41e12d2c79f799103813fd24c63bf7a964

    Properly mark the GDB line as busy
    
    	* src/dbgengine/nmv-gdb-engine.cc (issue_command): Mark the line
    	as busy when we send data over the wire.  The line is later marked
    	non-busy when we receive the proper marker from GDB.
    	(launch_gdb_and_set_args): Don't send data over the wire if it's
    	busy.
    	(on_gdb_stdout_has_data_signal): Slight indentation cleanup.
