bug#34939: Some minibuffer behaviour is annoying

Just to clarify myself.
I didn't mean that the error message was strange.
The fact that the message pops up at all is my concern.
It's maybe is OK for newcomers, 
but an option to not show - not to give any textual feedback - is what I had in 
mind.

Hmmm, no easy way to replace C-g... could it be made possible
to let the user slip in a custom key+function pair into the response 
option stack "(y, n, !, ., q, C-r, d or C-h)"?
