using ctrl-r ctrl-w does autocomplete expected word

[k-times-c]

as a continuation of #8 , sometimes I "autocomplete" a word I want to substitute with the '<,'>s/foo/bar/g command. so i can hit the first few letters of the word, then hit ctrl-r ctrl-w and then finish up the completion. the issue is that pressing ctrl-r ctrl-w just grabs the word at the beginning of the line that is visually highlight with this plugin..

I look forward to your thoughts.. Feel free to reach out with any questions.
