I agree this is weird but I have not found any better solution without
changing the core gdb.

The problem is that the TUI must know that a gdb command is being executed.
This way, if it interacts with the user, it has to be in the mode
where a prompt is displayed.

If we add some boolean predicate function that tells us we are executing some
command (whatever the command, a user, a set, a show, ...) this would
be fine for me.
Some kind of 'is_executing_command_p'.

Another way is to get an observer that allows the TUI to know when a command
is finished. This way, it could do switch the TUI back to the
SingleKey once the command
is done.  Adding an observer for this looks a little bit overkill.

If anybody has a better solution, I would appreciate it too!
