- Add |anyapplied, |anyunapplied, |anycount, and |nondefault filters.
- |anyapplied, |anyunapplied, |anycount, are filters to patch and when applied will make
 change the behavior so that if no patches are present then nothing will be printed
- |nondefault is a filter for branch that will stop anything being printed if the branch
 is the default one.  So only non-default branches are printed.
