Pol, It's the same set of limitations. Git does not track renames or copies as such. It uses heuristics to compute a similarity index and then decide. All the tree stores for your copy is a file add, and that's the status you're seeing. I don't think there is any way to turn on aggressive copy detection for git status. However, before you run git commit, you could run git diff --find-copies-harder --cached instead and it should show the copy. I'll let someone a little more intimately familiar with the internals of git status comment on why the documentation for that mentions copies.
