But isn't that better than not showing anything at all (which is what
will happen with the current code)?  Suppose we are talking about a
terminal where x-show-tip doesn't work at all, like a TTY with a
mouse, or when tooltip-mode is turned off?

I'd rather suggest that you call tooltip-show-help-non-mode directly
when tooltip-use-echo-area is non-nil.  Or am I missing something?
