Not as `symbol-name' values, they don't.

The point is to show the symbol _name_, and to do so in a
way that is clear to anyone.

"bar\ is a Lisp function." is not only unclear; it is incorrect.

And if you want to be pedantic, and you think there is already
no room for ambiguity, substitute "possible confusion".  Emacs
is not being as clear as it could be, and that is especially
important for someone new to Emacs and Emacs Lisp.
