[PATCH v2 0/2] git branch: allow combining merged and no-merged filters

Enable ref-filter to process multiple merged and no-merged filters, and extend functionality to git branch, git tag and git for-each-ref. This provides an easy way to check for branches that are "graduation candidates:"

$ git branch --merged next --no-merged master

Currently, this required a command like:

$ grep -xf \
  <(git branch --merged next) \
  <(git branch --no-merged master)

Also, add tests describing git branch's behavior when combining multiple contains/no-contains filters - this helps demonstrate consistency between merged/no-merged and contains/no-contains.
