I am not a UX designer, but for me, in the context of interaction with a 
command line program, any question that does not accept a reply is bad design. 
That also means that any command that does not run interactively should not 
ask questions. The shell interface is too informal to allow being loose on the 
program side. Comparatively to a GUI, where a label is formally informative 
and a popping-up dialog box asks for user input.

This patch should indeed be squashed with the first one. They are small changes 
in strings printed when dying.  They would share the more extended commit 
message.
