It does say that in the manual. What's confusing me is that (if I've read
this right), list-prompt uses a default if you don't set it to the empty
string, and select-prompt is the other way round. I think I've handled
that difference in the following.
This adds select-prompt to compinstall and corrects the menu at the
previous level (I had moved handling of scrolling but hadn't changed the
description in the menu).
