    (let ((not-default

          (default
	    'foo))
      )


(default 'foo) is not a call to the function `default'.
It's a list which is not an expression.
The bug here is that the indentation of that list
pays attention to something about `default'.

The same problem occurs with explicit indentation specs:

(let ((defun
          foo)
      (defmacro
          bar)
      )
  )

The fix would be to make indentation understand
the structure of a binding list.
That might be nontrivial work, but it would make a bigger
improvement in the indentation.

It does show something.  I think it shows that if we introduce a
category of macros without any special heuristic for them, the absence
won't draw much in the way of complaints.

But it doesn't show that we are better off not introducing the
heuristic, nor that it is wise to delete such a heuristic if we have
been accustomed to using one.
