patch: use a short, fixed-size message for last line of prompt (issue6158)
See issue6158 and the previous commit for examples of what might go wrong if we
have some combinations of readline version and terminal and need to wrap the
line.
Briefly: readline may not display the beginning of the last line of the prompt,
or it may print over it with the end of the prompt, making it difficult for
users to know what's going on.
