Re: [PATCH v3 4/5] difftool: Use symlinks when diffing against the worktree

David Aguilar [off-list ref] writes:

Teach difftool's --dir-diff mode to use symlinks to represent
files from the working copy, and make it the default behavior
for the non-Windows platforms.

Using symlinks is simpler and safer since we do not need to
worry about copying files back into the worktree.
The old behavior is still available as --no-symlinks.

Handles the case where an editor unlinks the original symlink,
replacing it with a file.

Thanks; will replace.
