If there is another way to solve this, please let me know. Wrapping git-receive-pack with a shell script to call umask seemed like too global a change. (also http://git.openswan.org/git#umask_hack)
When working with a common git repository, not all users are always clueful enough to set their umask properly --- nor should the default for the user always be so permissive.
This change adds $GIT_DIR/umask to contain a single line, an integer which will be fed to umask(). This should also work for the git daemon, which I personally do not use, so this may be inappropriate.
