Not calling `Clear` could only influence the results if the `Clear` previously
deleted existed completions from the list (which from what I can tell never
happens and if would be a bug). It's most likely just a failsafe because we
return 0 from this function (which has the match the size of match array).
================
Comment at: source/Interpreter/Options.cpp:731-741
- // The options definitions table has duplicates because of the
- // way the grouping information is stored, so only add once.
- bool duplicate = false;
- for (size_t k = 0; k < request.GetMatches().GetSize(); k++) {
- if (request.GetMatches().GetStringAtIndex(k) == full_name) {
- duplicate = true;
- break;
----------------

The `AddCompletion` is already checking for duplicates, so this code becomes
redundant. Actually, the only reason `AddCompletion` is checking for duplicates
is to make this code redundant (as one can't implement duplicate filtering
without read access to the match list, which we removed in this patch).
