I don't always write docstrings, but when I do, sometimes I only write half of them and then I feel silly. :-/
Documentation clarification to make the explanation of /etc/salt/grains more specific.
When the minion refreshes its grains, it should also refresh its pillars so that it can fire an event back to the master to inform it of its new state. Refs #5737.
In-line documentation to remind the reader that some pre-processing of minion targets occurs on the master.
Merge pull request #7929 from cachedout/develop

Fix for #5737 and some minor doc changes.
