I agree that it is confusing.  It seemed at since the variable was
already auto_boolean, it was already established that "auto" could mean
"ask" in some contexts.  "set breakpoint pending" command is using
"auto" in a similar way, though, surprisingly, there aren't that many
setshow_auto_boolean commands; and we don't need to make the same
mistake here.

I looked around for other three-state commands, and didn't find
reusable patterns, which made me drop the idea of
generalizing this, but there's a chance I didn't look right.

I think the best is to make this an enum command with
the three options ask|on|off, or perhaps better yet, ask|yes|no, as
attached?
