3821 | * however, deleting or adding an entry may have cascading effect. | |
3822 | * | |
3823 | * Say the "foo/bar/file" has become untracked, we need to tell the | |
3824 | * untracked_cache_dir of "foo" that "bar/" is not an untracked | |
3825 | * directory any more (because "bar" is managed by foo as an untracked | |
3826 | * "file"). | |

3830 | * "foo/" instead. Which means we have to invalidate past "bar" up to | |
3831 | * "foo". | |

3836 | * sophisticated way than checking for SHOW_OTHER_DIRECTORIES to | |
3837 | * detect these cases and avoid unnecessary invalidation, for example, | |
