Subject: Merge branch 'ts/doctar' into next
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=2c57ebc22329e11fc4843f62fe464a4e0c212176;p=git.git

Merge branch 'ts/doctar' into next

* ts/doctar:
  Documentation/Makefile: create tarballs for the man pages and html files
  SubmittingPatches: The download location of External Editor has moved
  Make git-check-format-ref a builtin.
  Make "git rev-list" be a builtin
  builtin-diff: do not say files are renamed when blob and file are given
  Provide a way to flush git-diff-tree's output
