I have git version 1.5.6.5 and for me your recipe[1] ends in

	$ git status
	# On branch t/test1
	nothing to commit (working directory clean)

With git 1.6.1.3 I can reproduce it though.

Here comes a git only test case:

	git init
	touch file
	git add file
	git commit -m 'initial commit'
	git checkout -b next
	echo next > file
	git add file
	git rm -f file
	git checkout master
	git status
	
What about the patch below?  It seems git-checkout from 1.6.x merges the
changes done to the newly checked out branch.

Best regards
Uwe

[1] I had to use mkdir where you wrote md ;-)

Subject: [PATCH] suggest checkout -f to abort the creation of a branch

git checkout behaves differently for different versions of git (here
1.5.6.5 and 1.6.1.3) when the index and working copy don't match HEAD.

git checkout -f does the right thing for both versions.
