Your patch does not work because it would unconditionally remove 
/usr/bin/zsh even if it were still needed because another package 
providing /bin/zsh is still installed.
It also checks in preinst that /usr/bin/ksh is not a broken link, 
because I suppose that this could happen and then without this check 
the script would fail.

Please let me know if this patch is acceptable, I have similar ones for 
mksh and ksh.
