Due to upgrading an app to be PSR-0 complient (uppercase class file names) I have changed classes to have uppercase filename. ie. users.php has become Users.php. That's worked fine and git has noticed the changes and pushed to the remote repo.
My problem is that if I now change the contents of Users.php at all. Both the old users.php and new Users.php appear as changed files to be staged.
How do I get git to forget about the lowercase version of the file?
Note. I'm using osx which ignores casing.
