Why?

The interactive form is either a string or code.  When it's a string,
I expect you get the one and only `(interactive THE-STRING)`, but when
it's not a string ... well ... by definition the compiler changes the
representation of code so it's completely expected that you won't get
necessarily quite the same code (as long as its execution is equivalent).

> The doc string doesn't make this clear, and needs amending anyway.

Maybe, but I don't understand why you think it's necessary.

And this suggests we should also document `symbol-function` to say that
it may not return something identical to what you wrote in the
source code.
