 *    it is given, "shorthand" branch names (i.e. those not prefixed by
 *    `refs/`, but consisting of a single word without `/` separators)
 *    become valid. For example, "main" would be accepted.
 * 3. If `ReferenceFormat.RefspecPattern` is given, the name may
 *    contain a single `*` in place of a full pathname component (e.g.
 *    `foo/*\/bar`, `foo/bar*`).
 * 4. Names prefixed with "refs/" can be almost anything. You must avoid
 *    the characters '~', '^', ':', '\\', '?', '[', and '*', and the
 *    sequences ".." and "@{" which have special meaning to revparse.

 * supposed to be ignored.
 *
 * Submodule info is contained in 4 places: the HEAD tree, the index, config
 * files (both .git/config and .gitmodules), and the working directory.  Any
 * or all of those places might be missing information about the submodule
 * depending on what state the repo is in.  We consider all four places to
 * build the combination of status flags.
 *
 * There are four values that are not really status, but give basic info
 * about what sources of submodule data are available.  These will be
 * returned even if ignore is set to "ALL".
 *
 * * IN_HEAD   - superproject head contains submodule
 * * IN_INDEX  - superproject index contains submodule
 * * IN_CONFIG - superproject gitmodules has submodule
 * * IN_WD     - superproject workdir has submodule
 *
 * The following values will be returned so long as ignore is not "ALL".
 *
 * * INDEX_ADDED       - in index, not in head
 * * INDEX_DELETED     - in head, not in index
 * * INDEX_MODIFIED    - index and head don't match
 * * WD_UNINITIALIZED  - workdir contains empty directory
 * * WD_ADDED          - in workdir, not index
 * * WD_DELETED        - in index, not workdir
 * * WD_MODIFIED       - index and workdir head don't match
 *
 * The following can only be returned if ignore is "NONE" or "UNTRACKED".
 *
 * * WD_INDEX_MODIFIED - submodule workdir index is dirty
 * * WD_WD_MODIFIED    - submodule workdir has modified files
 *
 * Lastly, the following will only be returned for ignore "NONE".
 *
 * * WD_UNTRACKED      - workdir contains untracked files
