Thanks for the quick reply. I did think about the PS1 being a problem.  Everything is surrounded with 
%{    %}.   I'll try a more basic prompt and let you know.  -----------------------------dave

 using 5.0.7 (Debian 8) in urvxt. I also tested in xterm and
 get the same result, strangely it doesn't happen on a
 console. I tried zsh -l in urxvt and get the same double
 letter result, but in xterm it is fine! Running a bare
 "compinit" without any extras doesn't make any
 difference. Has anyone else noticed this? I'm baffled

 You clearly
 have some problem with prompt. Most likely you forgot to
 surround something in PS1 with %{ … %} and zsh was no
 longer able to determine real prompt width. When you do
 completion in some cases zsh needs to redraw command text in
 which case it basically does “go to position {just after
 the place where PS1 ends} and print ‘cd …’”. If
 position is wrong you see what you see, but zsh still knows
 that it needs to run “cd …” and not “ccd …”.
 
 Except for missing %{ … %}
 there is another possible reason for this: zsh thinks that
 some character is double width, but terminal emulator thinks
 it has single width. If this is the case I do not know how
 to fix this cleanely (it is always possible to construct
 some hack).
 
 In any case you
 need to check your PS1.
