Well, for it to do the example given, it needs to be called every time
zle is started for whatever reason.  I think that's the only consistent
thing to do by default.

It should be possible to get more control, though.  You can already test
for context, e.g. $PREBUFFER.  Another zle variable giving more about
the context is a possibility.

Not in zsh, I just tend to use it for compatibility.
