The behaviour is as I would expect from the documentation.

I would find this behaviour confusing.  In any case, the "set confirm off"
command is for interactive use, not front ends.

Here's a revised patch for my original request.  It doesn't help with issues
relating to GDB/MI but just uses the "server prefix" instead of a special
option.  I have used this trick previously (2007-07-10) to avoid setting the
convenience variable $_ with breakpoints.  This seems appropriate as I think
the "server" command was created many years ago by Tom Lord or Jim Kingdon for
use with annotations.  I could add a suitable note to the documentation.
