Re: [PATCH 1/4] submodule: fix recursive path printing from non root directory

Recursing into submodules currently works by just calling
(cd $submodule && eval <command>) for update, sync and status
command.

Say you have the following setup

repo/ # a superproject repository
repo/untracked/ # an untracked dir in repo/
repo/sub/ # a submodule
repo/sub/subsub # a submodule of a submodule

When being in repo/untracked/ and invoking "git submodule status"
you would expect output like:

    repo/untracked/$ git submodule status --recursive
     <sha1> ../sub (version)
     <sha1> ../sub/subsub (<version>)

We need to take into account that we are in the untracked/ dir,
so we need to prepend ../ to the paths. By using relative_path
to compute the prefix, we'll have that output.
