bug#69226: 29.2.50; elisp-flymake-checkdoc complains about mentioning defclass

[Spencer Baugh]

1. emacs -Q
2. Create file containing:
(defclass my-class () ())
(defvar my-value nil
 "A useful value.

Should be of type `my-class' or nil")
(defun my-func ()
"Does something.

The return value is of type `my-class'.")
3. M-x flymake-mode
4. Observe warnings about:
Disambiguate my-class by preceding w/ function,command,variable,option or 
symbol.

The issue is that `my-class' is both a variable and a function.

I could rewrite the docstrings to say
"Should be produced by the function `my-class', or nil."
"The return value is produced by calling the function `my-class'."

but that's awkward wording.

It would be nice if checkdoc would recognize "type" before a quoted
symbol as removing the ambiguity.

Also, it might be nice if the docstring parser recognized "type" as
indicating that it should link to the function definition, not the
variable definition, since the variable definition is deprecated anyway.
