Or absolute path. I was thinking about absolute path, but path
relative to GIT_DIR of superproject is a good idea.

Why Pasky?

Very good idea, both using '.' to mark that submodule objects are in
the superproject objects database, and no value for not available
(although I'm less sure about the latter).


I am thinking about the following sequence to search for submodule
objects:

>From $GIT_DIR/config:
  submodule.$name.objects (absolute or relative to gitdir of superproject)
  submodule.$name.gitdir  (absolute or relative to gitdir of superproject)
  submodule.$name.url     (to find GIT_DIR, if it is local filesystem URL)

If there is working directory, from .gitmodules file in top level
of working directory:
  submodule.$name.path/.git (relative to toplevel of working directory)

What do you think about this?
