Thanks Mike
I wonder how tickets with positive review are merged into Sage. The
following two have positive review and were not included. Is something
wrong with the patches? Or should the tickets simply wait for
inclusion?

http://trac.sagemath.org/sage_trac/ticket/7325
http://trac.sagemath.org/sage_trac/ticket/6479

Many thanks
Robert
