When files are unmerged they can show up as both unmerged and modified in the output of `git diff --raw`. This causes difftool's dir-diff to create filesystem entries for the same path twice, which fails when it encounters a duplicate path. Ensure that each worktree path is only processed once. Add a test to demonstrate the breakage. Reported-by: Jan Smets <jan@smets.cx> Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
