freelinking must be sitting up to ignore the white spaces in title ends

I think freelinking must be sitting up to ignore the white spaces which could appear in title ends when it is written in [[..]] brackets

For example, if you have already a node titled as "yyy"
and want to link to it by [[ yyy ]] then freelinking will regards this title in the brackets as non exists because it has some space in the ends, and then freelinking module prompt to create a node for it which leads to extreme confuse in nodes titles
