buffer: throw "friendly" exception if question is too long

If a question is too long to fit on screen, the buffer manager currently
throws a hard-to-understand exception deep down in the buffer logic.
Explicitly checking for this condition and throwing a descriptive exception
makes life easier for hook authors.
