File permissions changed after Git Status > "Save Changes" button pushed.

[jonathanhatch]

I've created a custom theme. I had to change file permissions to allow RW for all groups/users/others to get Gitium to see that I was making changes to the files. However, after saving a change (say, version of style.css file) and pushing "Save changes" in the Git Status page, any file I've made changes to has its file permissions changed and I can no longer make changes to that file (without using sudo).

Thoughts?
