Junegunn Choi 92a75c9563 Use trimmed length when --nth is used with --tiebreak=length
This change improves sort ordering for aligned tabular input.
Given the following input:

    apple   juice   100
    apple   pie     200

fzf --nth=2 will now prefer the one with pie. Before this change fzf
compared "juice   " and "pie     ", both of which have the same length.
