Merge branch 'master' into db/fetch-pack

There's a number of tricky conflicts between master and
this topic right now due to the rewrite of builtin-push.
Junio must have handled these via rerere; I'd rather not
deal with them again so I'm pre-merging master into the
topic.  Besides this topic somehow started to depend on
the strbuf series that was in next, but is now in master.
It no longer compiles on its own without the strbuf API.

* master: (184 commits)
  Whip post 1.5.3.4 maintenance series into shape.
  Minor usage update in setgitperms.perl
  manual: use 'URL' instead of 'url'.
  manual: add some markup.
  manual: Fix example finding commits referencing given content.
  Fix wording in push definition.
  Fix some typos, punctuation, missing words, minor markup.
  manual: Fix or remove em dashes.
  Add a --dry-run option to git-push.
  Add a --dry-run option to git-send-pack.
  Fix in-place editing functions in convert.c
  instaweb: support for Ruby's WEBrick server
  instaweb: allow for use of auto-generated scripts
  Add 'git-p4 commit' as an alias for 'git-p4 submit'
  hg-to-git speedup through selectable repack intervals
  git-svn: respect Subversion's [auth] section configuration values
  gtksourceview2 support for gitview
  fix contrib/hooks/post-receive-email hooks.recipients error message
  Support cvs via git-shell
  rebase -i: use diff plumbing instead of porcelain
  ...
