How about Plot? Plot does evaluate its arguments in a non-standard way as compared to say Exp or Sqrt. So, some functions do affect the way their arguments are evaluated.

I agree there are several aspects of the documentation that could be made clearer and that the documentation for "wrapper" functions like BaseForm or Matrix form is an example of documentation that could be made clearer. I don't agree the documentation is clearly incorrect.
