OK, that's good to know.

I checked in two changesets that should make this feature work.  Now 
what's left is to tag built-in functions with the classes that they 
handle.  The changes I checked in show what is needed using svd as an 
example:

  DEFUN (svd, args, nargout,
         classes: double single
         doc: /* -*- texinfo -*-
  @deftypefn  {} address@hidden =} svd (@var{A})
  ...

The class names should be the built-in class names like double, single, 
logical, char, cell, struct, etc.  This is the string returned by the 
class function for an object NOT the name of the internal type used by 
Octave.
