Issue 5740: Add \post to defer context actions to end of time step (issue 581600043 by nine.fierce.ballads@gmail.com)

Hi Dan,

I've difficulties to understand what this is about. And my lack of
C++-knowledge hinders my to deduce it.
Could you give a ly-code-example which is not possible with current
possibilities or where using current possibilities leads to some
uglyness?
