Question completion style.

[Ergus]

Hi:

The new flex completion style seems to be very useful and should work in
most of the cases. My question is about what is the best (suggested)
configuration for it. I see that completion-styles already have 3 values
do you thing is more useful to append || prepped || replace one of the
actual values || set just flex....?

Which one should give a good list of candidates in most of the cases
without killing performance?

Thanks In advance,
Ergus
