[PATCH 0/2] difftool --dir-diff: symlink all files matching the working tree

Here's the proper patch. It grew into a series because I noticed a minor formatting error in the difftool documentation, which the first commit fixes.

The content of the second patch is the same as was previously posted.

John Keeping (2):
  git-difftool(1): fix formatting of --symlink description
  difftool --dir-diff: symlink all files matching the working tree
