There is no longer any code which references the single-byte comment_line_char. Let's drop it, clearing the way for true multi-byte entries in comment_line_str.

It's possible there are topics in flight that have added new references to comment_line_char. But we would prefer to fail compilation (and then fix it) upon merging with this, rather than have them quietly ignore the bytes after the first.
