Merge branch 'cw/log-updates-for-all-refs-really'

The "core.logAllRefUpdates" that used to be boolean has been
enhanced to take 'always' as well, to record ref updates to refs
other than the ones that are expected to be updated (i.e. branches,
remote-tracking branches and notes).

* cw/log-updates-for-all-refs-really:
  doc: add note about ignoring '--no-create-reflog'
  update-ref: add test cases for bare repository
  refs: add option core.logAllRefUpdates = always
  config: add markup to core.logAllRefUpdates doc
