| Furthermore, in Octave 3.0.0 "whos A.a" prints the fields of the

I consider the new behavior to be correct.  The who and whos functions
look for symbol names.  A.a is not a symbol name so can't match an
entry in the symbol table.  Is this worth fixing in 3.0.x?  I guess I
would consider a patch.
