       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.
