Comment (by rbeezer):

 I'd like to have the `sage_input()` command preserve the subdivisions of
 matrix.  So the output of `sage_input(A)` could be something like

 {{{
 matrix(QQ, [[1,2,3], [4,5,6]]).subdivide([1], [2], copy=True)
 }}}

 '''presuming''' the copy option proposed here was functional.  So this
 ticket is a precursor to the upcoming `sage_input` ticket.  Work on the
 present ticket is close to finished.
