* no option to include all files in directories that are ignored
* completely.
* - GIT_STATUS_OPT_INCLUDE_UNMODIFIED indicates that callback should be
* made even on unmodified files.
* - GIT_STATUS_OPT_EXCLUDE_SUBMODULES indicates that directories which
* appear to be submodules should just be skipped over.
* - GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS indicates that the contents of
* untracked directories should be included in the status. Normally if

* included (with a trailing slash on the entry name). Given this flag,

* will.

* will be treated as a literal path, and not as a pathspec.
