Maybe something like this.  I'm still unsure about providing a prefix
message without keys, because when the message arg is a string
then better to display it as is.  Otherwise when it is `t', then
the message will be constructed to "Repeat with <keys...>".
I.e. the remaining question is that you already raised whether
typically all keys should be mentioned in the message.

OTOH, there are messages like "Use \\`+',\\`-',\\`0' for further adjustment"
have not only a prefix, but also a suffix.
