I've tried propertizing other parts of the string and finding the
position with `text-property-not-all' in the annotation function.
Unfortunately this did not work since the quoting in
`completion--twq-all' recreates the entire string. However it can happen
that the string content after quoting just stays the same. This is what
I tried to use in my patch, by just returning the original string in
that case.
