It's inconsistent, though.  If you use no-select by itself, it kills
MENUSELECT.  And the doc suggests that it should always prevail:

     Menu selection can be turned off explicitly by defining a value
     containing the string 'no-select'.

I had an example but it's long since scrolled out of my terminal history.

Sorry, I mis-"spoke" there.  I meant "from a generic widget" not
literally "_generic".

The initial widget is not a zle -C widget, it's a zle -N that fiddles
around with $BUFFER, sets up $curcontext, and then runs "zle
_correct_word".

But given this:

if [[ -z "$curcontext" ]]; then
  curcontext="correct-word:::"
else
  curcontext="correct-word:${curcontext#*:}"
fi

I don't see how the function context can ever be anything other than
"correct-word", even if it was started from _generic?  Unless the
style is tested either before _correct_word is called or after it
returns.
