Merge branch 'master' into js/fmt-patch

* master: (109 commits)
  t1300-repo-config: two new config parsing tests.
  Another config file parsing fix.
  update-index: plug memory leak from prefix_path()
  checkout-index: plug memory leak from prefix_path()
  update-index --unresolve: work from a subdirectory.
  pack-object: squelch eye-candy on non-tty
  core.prefersymlinkrefs: use symlinks for .git/HEAD
  repo-config: trim white-space before comment
  Fix for config file section parsing.
  Clarify git-cherry documentation.
  Update git-unpack-objects documentation.
  Fix up docs where "--" isn't displayed correctly.
  Several trivial documentation touch ups.
  git-svn 1.0.0
  git-svn: documentation updates
  delta: stricter constness
  Makefile: do not link rev-list any specially.
  builtin-push: --all and --tags _are_ explicit refspecs
  builtin-log/whatchanged/show: make them official.
  show-branch: omit uninteresting merges.
