    Trim trailing whitespaces in every selection case
    
    Trailing whitespaces are trimmed when copying from normal selection and
    rectangular selection on lines that have their last character included
    or on the left of the selection. It leads to inconsistent behaviors when
    copying the exact same text from the left and right window in
    applications with vertical splits.
    This patch solves this issue by always trimming the selection.
