Thanks for the explanation. 

You initially spoke of limiting the "size" to the "window caption" (frame title, I guess). I thought you meant width too. Please do not impose a width limit, especially one that depends on the width of the current frame title. That's the main objection I had.

I think now that you're speaking only of imposing a frame height limit, not a width limit. I guess you're saying that a width limit is already imposed by the system, and that is roughly the width of the icons used in the title bar, plus maybe two title characters (at least that's what I see in your image). Is that correct? Do you just want to limit the height, not the width? If so, what is the height limit that you want to impose - one frame-char height? Why? 

I still don't understand the problem you are trying to fix. You mention only ugliness. That's not a good reason to impose a size limitation, IMO. Someone might have a reason to shrink a frame to a tiny size, perhaps in a way that is unrelated to character size. And people who don't want to shrink to such a tiny size just won't do it. What does it hurt to allow this? What is the real need for such a change? Did you run into a problem and somehow ended up with a frame like the one you sent an image of? Please describe the real problem.

If it aint broke don't fix it, please. (Or, as someone here is wont to say, "No one has ever complained about that before" ;-).)

I have code that resizes frames, and it lets users set their own minimum frame dimensions. I would not like Emacs to impose some hard-coded minimum. If a given OS or window manager imposes a minimum, so be it, but why make Emacs impose a minimum also?
