There is a pattern, don't you see that :-) ?  There is an empty pattern.

The

[[ ${#reply[(r),-1]} != 0 ]] && reply[(r)]="''"

line just replaces an empty array element with a '' since zle_tricky does
not properly quotes empty strings.  Unfortunately replacing the empty sring
to '' in quotename() does not help since it messes up completion if there
is an empty string in the list.
