Merge branch 'master' into np/index-pack

* master: (90 commits)
  gitweb: Better support for non-CSS aware web browsers
  gitweb: Output also empty patches in "commitdiff" view
  gitweb: Use git-for-each-ref to generate list of heads and/or tags
  for-each-ref: "creator" and "creatordate" fields
  Add --global option to git-repo-config.
  pack-refs: Store the full name of the ref even when packing only tags.
  git-clone documentation didn't mention --origin as equivalent of -o
  Minor grammar fixes for git-diff-index.txt
  link_temp_to_file: call adjust_shared_perm() only when we created the directory
  Remove uneccessarily similar printf() from print_ref_list() in builtin-branch
  pack-objects doesn't create random pack names
  branch: work in subdirectories.
  gitweb: Use 's' regexp modifier to secure against filenames with LF
  gitweb: Secure against commit-ish/tree-ish with the same name as path
  gitweb: esc_html() author in blame
  git-svnimport: support for partial imports
  link_temp_to_file: don't leave the path truncated on adjust_shared_perm failure
  Move deny_non_fast_forwards handling completely into receive-pack.
  revision traversal: --unpacked does not limit commit list anymore.
  Continue traversal when rev-list --unpacked finds a packed commit.
