Hmm, it's not clear to me exactly what is allowed here.  Any
expression that evaluates to an appropriate number, or what?  (I
couldn't find anything about it in the manual).

Something like this works:

  (insert #(" " 0 1 (display (space :align-to (- fill-column 5)))))

But this doesn't work:

  (defun two () 2)
  (insert #(" " 0 1 (display (space :align-to (two)))))

Why?
