It does work, very well at that.

I have a directory for each separate branch and simply use
cd(1) to change the current working directory to that branch.
So, instead of "git checkout <branch>", I do "cd ../<branch>".

One only needs to watch out when one updates the repository.
If there had been updates in those branches, then one needs
to git-reset the "branch" directory... (you know what I mean)
(For example when I come to work in the morning an sync up
 with home from my usb key...)

The script is called:
Usage: git-mkdir-of-branch <original-directory> <branch> <new-directory>
  where <branch> is the name of an existing branch in <original-directory>/.git/refs/heads

and uses simple symbolic links and some git plumbing to do the
job.  It can be found in my git trees.  I never bothered to send
it out to Junio, since it could be considered heretic. ;-)
