52 * This is like a combination of ..LEADING_PATH and .._SLASH_CHEAP
53 * (but not the same): it strips the trailing slash if the given path
54 * is a gitlink but also checks and dies if gitlink is part of the
55 * leading path (i.e. the given path goes beyond a submodule). It's
56 * safer than _SLASH_CHEAP and also more expensive.
