title: git ignore file without deleting it on remote repository for all users
body: <p>I saw many questions regarding this issue but I didn't saw appropriate solution for this problem.
  lets say that I have a template.xml file in remote and I want all users to get it when they first cloning the repository but when they changing it will be ignored.
  I <em>assume-unchanged</em> but it is only locally and I would like to have a solution for all users</p>
