One real fix since v3: there was an incorrect file name in a test
(noticed by Jonathan). Now, all actual outputs are called "actual".

Other than that: extra tests, and style fixes in commit messages.

Matthieu Moy (6):
  t4000-diff-format.sh: modernize style
  diff: allow --no-patch as synonym for -s
  diff: allow --patch & cie to override -s/--no-patch
  Documentation/git-show.txt: include common diff options, like
    git-log.txt
  Documentation: move description of -s, --no-patch to diff-options.txt
  Documentation/git-log.txt: capitalize section names
