This all looks reasonable to me.  I have a few style nits.

This should be marked `static' (it is declared that way but it is
clearer to mark the definition as well).  I think it needs a header
comment.

Volodya>  static enum command_control_type
Volodya> -recurse_read_control_structure (struct command_line *current_cmd)
Volodya> +recurse_read_control_structure (char * (*read_next_line_func) (), 
Volodya> +				struct command_line *current_cmd)

The header comment should be updated to mention the new argument.
And if you don't mind, please fix the reference to the non-existing
"parent_control" parameter.

Volodya> +extern struct command_line *read_command_lines_1 
Volodya> +(char * (*read_next_line_func) (), int parse_commands);

Indentation on the 2nd line.

There's some other little style nits in the patch -- over-bracing in the
second patch, mostly.

Volodya> +void
Volodya> +breakpoint_set_commands (struct breakpoint *b, struct command_line *commands)

Needs a header comment.

Volodya> +static char **mi_command_line_array;
Volodya> +static int mi_command_line_array_cnt;
Volodya> +static int mi_command_line_array_ptr;

[...]

Volodya> +  break_command = read_command_lines_1 (mi_read_next_line, 0);

I think this would be cleaner if read_command_lines_1 took a "user_data"
argument and then there were no new globals.
