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. ...
