With the new compstate-keys we could almost avoid having to give the
name of a builtin completion widget to `zle -C' (since users can
re-implement anything). But I'd be against this, because (and this is
the answer to your question) I think it is very convenient to have a
simple way to set the initial values for the keys in a way that make
things behave like the widgets one is used to (if they are left
untouched by the widget). I.e. currently the `emulated' builtin widget
and the option settings are used to set the values when the completion
widget is called. After the widget exits, the code uses the current
values, so if the widget changed them, the behavior will differ. Of
course, options will not be altered by the code.
