From 89c8626557621ef000930da3c8a23fa03ad7e01a Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Thu, 8 Dec 2016 13:03:25 -0800 Subject: submodule helper: support super prefix Just like main commands in Git, the submodule helper needs access to the superproject prefix. Enable this in the git.c but have its own fuse in the helper code by having a flag to turn on the super prefix.

Add functionality to migrate the git directory to be absorbed into the superprojects git directory. The newly added code in this patch is structured such that other areas of Git can also make use of it. The code in the submodule--helper is a mere wrapper and option parser for the function `absorb_git_dir_into_superproject`, that takes care of embedding the submodules git directory into the superprojects git dir. That function makes use of the more abstract function for this use case `relocate_gitdir`, which can be used by e.g. the worktree code eventually to move around a git directory.
