* - GIT_STATUS_OPT_INCLUDE_IGNORED says that ignored files should get
* callbacks. Again, these callbacks will only be made if the workdir
* files are included in the status "show" option. Right now, there is
* 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
* an entire directory is new, then just the top-level directory will be
* included (with a trailing slash on the entry name). Given this flag,
* the directory itself will not be included, but all the files in it
* will.
* - GIT_STATUS_OPT_DISABLE_PATHSPEC_MATCH indicates that the given path
* will be treated as a literal path, and not as a pathspec.
*
* Calling `git_status_foreach()` is like calling the extended version
* with: GIT_STATUS_OPT_INCLUDE_IGNORED, GIT_STATUS_OPT_INCLUDE_UNTRACKED,
* and GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS.
