This is not an exception for comments: the `PenaltyExcessCharacter` is used whenever the code is longer than the `ColumnLimit`, and used to compute the best solution.
The default value is extremely high, so there is no practical difference: code does not go beyond the column, except for specific exceptions.

However, the difference becomes apparent when reducing this penalty: in that case, code can break the column limit instead of wrapping, but it does not happen with comments. This patch tries to restore the parity, and let comments break the comment limit as well.
