    vt: fix double-click word selection for first word on line
    
    Previously when double-clicking on the first word on a line we would
    select from the cursor position to the end of the word, not from the
    beginning of the line.  This is because we searched backward for a
    space to mark the beginning of a word.
    
    Now, use the beginning of the line if we do not find a space.
