    patch 8.1.0677: look-behind match may use the wrong line number

    Problem:    Look-behind match may use the wrong line number. (Dominique Pelle)
    Solution:   Use the line number in regsave instead of the one in behind_pos,
                we may be looking at the previous line. (closes #3749)
