* NEEDSWORK: The current way of mapping a submodule's name to
* its location in .git/modules/ has problems with some naming
* schemes. For example, if a submodule is named "foo" and
* another is named "foo/bar" (whether present in the same
* superproject commit or not - the problem will arise if both
* superproject commits have been checked out at any point in
* time), or if two submodule names only have different cases in
* a case-insensitive filesystem.
*
* There are several solutions, including encoding the path in
* some way, introducing a submodule.<name>.gitdir config in
* .git/config (not .gitmodules) that allows overriding what the
* gitdir of a submodule would be (and teach Git, upon noticing
* a clash, to automatically determine a non-clashing name and
* to write such a config), or introducing a
* submodule.<name>.gitdir config in .gitmodules that repo
* administrators can explicitly set. Nothing has been decided,
* so for now, just append the name at the end of the path.
