I think my last mail missed the point. `completion--replace` is supposed
to strip *all properties* since we are inserting the completed text in
the destination buffer. At this point the inserted/replaced text is to
be treated like user input and shouldn't carry any text properties,
neither text properties produced by completion, nor text properties
which were attached originally to the candidate strings.
