For me it is the opposite.

It just does not have a readable shape.

Similar to the "tabs vs spaces" debate, spaces/manual linebreaks prescribe the appearance of the code/text, whereas tabs/automatic line-breaking leave this decision to the tooling of the reader or author. If I resize my browser window, I would like its contents to be re-layouted as flexibly as possible.
