I've now looked at bug#38457, and the only fix I see there involves a
timer to remove the text displayed by minibuffer-message.  Whereas
Dmitry's report is about a commit which added calls to discard-input
to various places.  How can the proposed timer get back input that was
discarded?  What am I missing?
