[PATCH 0/2] Support relative .git file in a submodule

While experimenting with submodules I discovered that if a submodule has a .git file "symlink" with a relative path to the real submodule repository then it cannot be added to the superproject:

$ git init $ mkdir sub $ cd sub $ git init $ mv .git .real $ echo 'gitdir: .real' > .git $ echo a > a $ git add a $ git commit -m a $ cd .. $ git add sub fatal: Not a git repository: .real

This patch series adds a test demonstrating the problem, and then fixes it.

  Handle relative paths in submodule .git files
