Ram is plain wrong here (just like he is on "git rm" and "git mv",
even though the latter is currently still in pu). This use case is
handled by submodules for years now. Take a look at the "ignore"
setting in .gitmodules which give you full control of the stat()s
in submodules, in addition you have the repo-wide option
The whole feature list is full of red herrings like this which
have nothing to do with the advantages of a new object, but talk
about UI issues which are easy to solve in both worlds.
