There are two locations in prepare_to_clone_next_submodule() that manually calculate the submodule display path, but should just use do_get_submodule_displaypath() for consistency. Do this replacement and reorder the code slightly to avoid computing the display path twice. Until the preceding commit this code had never been tested, with our newly added tests we can see that both these sites have been computing the display path incorrectly ever since they were introduced in 48308681b0 (git submodule update: have a dedicated helper for cloning, 2016-02-29) [1]: - The first hunk puts a "/" between recursive_prefix and ce->name, but recursive_prefix already ends with "/". - The second hunk calls relative_path() on recursive_prefix and ce->name, but relative_path() only makes sense when both paths share the same base directory. This is never the case here: - recursive_prefix is the path from the topmost superproject to the current submodule - ce->name is the path from the root of the current submodule to its submodule. so, e.g. recursive_prefix="super" and ce->name="submodule" produces displayname="../super" instead of "super/submodule". [1] I verified this by applying the tests to 48308681b0.
