Unfortunately this is quite heavily tied to executing an interactive
command line, and I don't think turning on interactive mode for
executing the script is good enough either (though I haven't actually
tried).
You're best bet might be to use the DEBUG trap. If you define the
function as TRAPDEBUG instead of preexec it'll get called before each
command. The effect isn't quite the same, since it'll get called more
often than it would before a complete command line. You can examine
what is about to be executed in $ZSH_DEBUG_CMD (see the documentation
for the trap builtin).
