Sure, I just wanted to tighten the check in that function to the actual
form it was checking, instead of including the VAR form, too.  Nobody
would actually write something like that.

But speaking of other code that's mis-highlighted still:

(defun a (when b c)
  ...)

(The `when' isn't a keyword here, but it's font-locked as such.)

Couldn't we just use `edebug-form-spec' to notice that the arglist isn't
a funcall position?  That would get a huge number of macros/special
forms with non-funcall positions right...
`lisp--el-non-funcall-position-p' would have to parse that, though,
which might slow things down?
