[git] How do I force git to checkout the master branch and remove carriage returns after I've normalized files using the "text" attribute?

Okay, so I added the file .gitattributes with lines like this

*.css text
*.js text

I then followed the instructions at http://git-scm.com/docs/gitattributes#_checking-out_and_checking-in

$ rm .git/index     # Remove the index to force Git to
$ git reset         # re-scan the working directory
$ git status        # Show files that will be normalized
$ git add -u
$ git add .gitattributes
$ git commit -m "Introduce end-of-line normalization"

But now my working copy still has the carriage returns! I have untracked files that I would like to keep. How do I have git checkout the master branch again with the normalized files?

I know the files are normalized in the repository because when I clone the repo, I have all the files without the carriage returns.

The answer is

Ahah! Checkout the previous commit, then checkout the master.

git checkout HEAD^
git checkout -f master

As others have pointed out one could just delete all the files in the repo and then check them out. I prefer this method and it can be done with the code below

git ls-files -z | xargs -0 rm
git checkout -- .

or one line

git ls-files -z | xargs -0 rm ; git checkout -- .

I use it all the time and haven't found any down sides yet!

For some further explanation, the -z appends a null character onto the end of each entry output by ls-files, and the -0 tells xargs to delimit the output it was receiving by those null characters.
