MI has no provision for handling query functions

MI avoids queries generated by CLI commands by implicitly answering them in the
affirmative (by making deprecated_query_hook return 1).

This query arose (indirectly) from an MI command.  Only a few MI commands
deal with queries, e.g, -break-insert for pending breakpoints and and
breakpoint menus, and they just take a default action.

If you want to request for user interaction you will need to give MI a richer
set of output records.  Good luck!
