Do you think we can add a command to set the non-terminal query answer?
For example:
set non-terminal-query-default yes/no/auto
auto This is the default value. query/yquery/nquery answer will like before.
yes  query/yquery/nquery answer will be yes
no  query/yquery/nquery answer will be no

This is really a long issue.  I remember that someone said this issue
will be handle by MI after 7.0 release.
