I think there is a bug here:

+ mkdir bug
+ cd bug
+ git init
Initialized empty Git repository in /tmp/bug/.git/
+ mkdir dir1 dir2
+ echo 1
+ echo 1
+ echo 2a
+ echo 2b
+ git add dir1/1.txt dir1/2.txt dir2/1.txt dir2/2.txt
+ git commit -m first
[master (root-commit) b60ecc8] first
 4 files changed, 4 insertions(+)
 create mode 100644 dir1/1.txt
 create mode 100644 dir1/2.txt
 create mode 100644 dir2/1.txt
 create mode 100644 dir2/2.txt
+ rm -r dir2
+ ln -s dir1 dir2
+ git status
On branch master
Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working
directory)

	deleted:    dir2/2.txt

Untracked files:
  (use "git add <file>..." to include in what will be committed)

	dir2

no changes added to commit (use "git add" and/or "git commit -a")

It looks like git status is thinking dir2/1.txt still exists with the
same content, even though dir2 is gone, and now an untracked symlink. 

Moreover, git diff and git status disagree with each other:

dennis@spirit:/tmp/bug$ git status
