It looks like the problem is due to the way fvwm (my window manager of choice)
does opaque resizing.  It is doing exactly what you say, six resizes of one
line each.  I happen to enjoy opaque resizing quite a bit, but maybe I'll turn
it off for my xterms.  That's kind of an annoying work-around though, and I'll
still get an extra line every time I resize.  I just may end up doing more
resizing with opaque resize off as well, since I'm not exactly sure what I'm
going to be seeing when I release the mouse button, and this will contribute
more annoying lines.  

Am I correct in concluding from your reply that it is impossible to have a
multi-line zsh prompt and not get any extra lines after resizing a terminal?
