} The test is done in zlevarsetfn() in params.c.

Yeah, but all it does is pretend the terminal is very narrow and set the
imaginary columns and lines to 80 and 24.

A zero value in shttyinfo.winsize is a special indicator from the driver
that it doesn't know what the window size is.  The actual window shape
in that case is read from the termcap by most applications.  It doesn't
mean that the window is actually zero sized.

I should have remembered this when I was fiddling with this code some
months ago; I remembered it a few weeks later when Geoff was hacking on
the zle refresh stuff, and mentioned it on the list.

The same test should probably go in adjustwinsize, but I don't think the
driver ever sends SIGWINCH when it doesn't know the window shape, so it
isn't as important there.
