patch 8.0.0423: changing 'cinoptions' does not always work

    patch 8.0.0423: changing 'cinoptions' does not always work

    Problem:    The effect of adding "#" to 'cinoptions' is not always removed.
                (David Briscoe)
    Solution:   Reset b_ind_hash_comment. (Christian Brabandt, closes #1475)
