[PATCH v2 0/5] difftool: Use symlinks in dir-diff mode

Teach the difftool script to use symlinks when doing directory diffs in --dir-diff mode.

This is v2 of the patch because I had a typo in one of the commit messages and gmail ate 4/5 in the last round.

David Aguilar (5):
  difftool: Simplify print_tool_help()
  difftool: Eliminate global variables
  difftool: Move option values into a hash
  difftool: Call the temp directory "git-difftool"
  difftool: Use symlinks when diffing against the worktree
