web-search plugin: unwanted output to nohup.out

When calling `google something`, a warning appears and it ask to remove nohup.out (interactive rm enabled).
This fix avoid creating nohup.out

    nohup: ignoring input and appending output to ‘nohup.out’
    rm: remove regular empty file ‘nohup.out’?
