Additional GIT Features and Updates

"--format=<style>". In addition, --format=%formatstring is a short-hand for --pretty=tformat:%formatstring. * "--oneline" is a synonym for "--pretty=oneline --abbrev-commit". * "--graph" to the "git log" family can draw the commit ancestry graph in colors. * If you realize that you botched the patch when you are editing hunks with the 'edit' action in git-add -i/-p, you can abort the editor to tell git not to apply it. * @{-1} is a new way to refer to the last branch you were on introduced in 1.6.2, but the initial implementation did not teach this to a few commands. Now the syntax works with "branch -m @{-1} newname". * git-archive learned --output=<file> option. * git-archive takes attributes from the tree being archived; strictly speaking, this is an incompatible behaviour change, but is a good one. Use --worktree-attributes option to allow it to read attributes from the work tree as before (deprecated git-tar tree command always reads attributes from the work tree). * git-bisect shows not just the number of remaining commits whose goodness is unknown, but also shows the estimated number of remaining rounds. * You can give --date=<format> option to git-blame. * "git-branch -r" shows HEAD symref that points at a remote branch in interest of each tracked remote repository. * "git-branch -v -v" is a new way to get list of names for branches and the "upstream" branch for them. * git-config learned -e option to open an editor to edit the config file directly. * git-clone runs post-checkout hook when run without --no-checkout. * git-difftool is now part of the officially supported command, primarily maintained by David Aguilar. * git-for-each-ref learned a new "upstream" token. * git-format-patch can be told to use attachment with a new configuration, format.attach. * git-format-patch can be told to produce deep or shallow message threads. * git-format-patch can be told to always add sign-off with a configuration variable. * git-format-patch learned format.headers configuration to add extra header fields to the output. This behaviour is similar to the existing --add-header=<header> option of the command. * git-format-patch
