Sure.  We just need a volunteer to submit a patch.  

However, this will require that a switch is added to the "source"
command syntax
and that will lead us to a long discussion on the syntax of switches
("\" or "-").

IMO, that is conceptually wrong.  The MI is not another command line
syntax -- it is
a machine protocol between two programs.  It was chosen to be in ASCII
and readable
for easy of debugging and implementation.

The idea is that the MI source command reads and executes commands (from
a file) that
are in the normal GDB command line (cli) script language.  It was not
implemented yet
because GDB is slowly being modified to allow switching the format of
commands on the
fly.  This requires adding parameters to functions and passing them down
so it takes
some time to do.


Thanks for the comments and suggestions.
