  gitweb: git_annotate didn't expect negative numeric timezone
  git-svn: add the 'dcommit' command
  git-svn: recommend rebase for syncing against an SVN repo
  git-svn: establish new connections on commit after fork
  describe: fix off-by-one error in --abbrev=40 handling
  git-svn(1): improve asciidoc markup
  gitview.txt: improve asciidoc markup
  git(7): put the synopsis in a verse style paragraph
  gitk(1): expand the manpage to look less like a template
  git-blame(1): mention options in the synopsis and advertise pickaxe

  update-index -g
  n is in fact unused, and is later shadowed.
  use name[len] in switch directly, instead of creating a shadowed variable.
  builtin-grep.c: remove unused debugging piece.
  remove ugly shadowing of loop indexes in subloops.
  missing 'static' keywords
  git_dir holds pointers to local strings, hence MUST be const.
  avoid to use error that shadows the function name, use err instead.
