Until a few minutes ago I'd have said it was something that needed to
be fixed in Terminal, but I may have found a zsh bug that's behind it
all.  I've sent a possible fix to zsh-workers for discussion.

I don't find any evidence that this helps except possibly by waiting to 
change the prompt until the first time the WINCH is received, which
would avoid the startup-time double prompt.  I still get the prompt
printed multiple times if I later resize the window.

However,

    trap 'tput cuu1' WINCH

(that is, move up one line on each WINCH signal) might work around it
for you.  If your prompt has more than two lines, you'll need to move
up one less than the number of lines in the prompt.
