The current implementation happens to chdir to GIT_DIR and sets
GIT_DIR=. in the environment, so if you have something like
this:

	/var/www/myproject/
	/var/www/myproject/.git/
	/var/www/myproject/.git/HEAD
	/var/www/myproject/.git/...
        /var/www/myproject/README

Then $(pwd) would be /var/www/myproject/.git/.  Your hook would
probably be able to do "cd .."  to get to the project top.

However, there is no guarantee for future implementations.
