display-buffer-at-bottom looks adequate for its purpose. I'm only 
pointing out that *completions* is very rarely _below_ where you are.

I don't want to write my own action because it'll just be another piece 
of logic behaving differently from the rest. Hardly a beneficial thing.

If we're emulating an IDE, though, the standard is to default to ~30% of 
the frame height, or less. The user might change the height, but even 
so, they're unlikely to increase it above 50% of the frame height, and 
in doing that, they'll cut the height of all file-visiting windows by half.
