[PATCH v2 0/3] difftool --dir-diff: symlink all files matching the working tree

Changes since v1:
- A new second patch to make it safer to compare symlink targets in
  tests
- Test in patch 3 (formerly patch 2) re-written thanks to feedback from
  David Aguilar

This series is based on next, although I think Git's clever enough to ignore the changes in the context of the t7800 hunk so it should apply to master as well.

John Keeping (3):
  git-difftool(1): fix formatting of --symlink description
  difftool: avoid double slashes in symlink targets
  difftool --dir-diff: symlink all files matching the working tree
