* Flags to control status callbacks
*
* - GIT_STATUS_OPT_INCLUDE_UNTRACKED says that callbacks should be made
* on untracked files. These will only be made if the workdir files are
* included in the status "show" option.
* - GIT_STATUS_OPT_INCLUDE_IGNORED says that ignored files get callbacks.
* Again, these callbacks will only be made if the workdir files are
* included in the status "show" option.
* - GIT_STATUS_OPT_INCLUDE_UNMODIFIED indicates that callback should be
* made even on unmodified files.
* - GIT_STATUS_OPT_EXCLUDE_SUBMODULES indicates that submodules should be
* skipped. This only applies if there are no pending typechanges to
* the submodule (either from or to another type).
* - GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS indicates that all files in
* untracked directories should be included. Normally if an entire
* directory is new, then just the top-level directory is included (with
* a trailing slash on the entry name). This flag says to include all
* of the individual files in the directory instead.
* - GIT_STATUS_OPT_DISABLE_PATHSPEC_MATCH indicates that the given path
* should be treated as a literal path, and not as a pathspec pattern.
* - GIT_STATUS_OPT_RECURSE_IGNORED_DIRS indicates that the contents of
* ignored directories should be included in the status. This is like
* doing `git ls-files -o -i --exclude-standard` with core git.
* - GIT_STATUS_OPT_RENAMES_HEAD_TO_INDEX indicates that rename detection
* should be processed between the head and the index and enables
* the GIT_STATUS_INDEX_RENAMED as a possible status flag.
* - GIT_STATUS_OPT_RENAMES_INDEX_TO_WORKDIR indicates that rename
* detection should be run between the index and the working directory
* and enabled GIT_STATUS_WT_RENAMED as a possible status flag.
* - GIT_STATUS_OPT_SORT_CASE_SENSITIVELY overrides the native case
* sensitivity for the file system and forces the output to be in
* case-sensitive order
* - GIT_STATUS_OPT_SORT_CASE_INSENSITIVELY overrides the native case
* sensitivity for the file system and forces the output to be in
* case-insensitive order
* - GIT_STATUS_OPT_RENAMES_FROM_REWRITES indicates that rename detection
* should include rewritten files
* - GIT_STATUS_OPT_NO_REFRESH bypasses the default status behavior of
* doing a "soft" index reload (i.e. reloading the index data if the
* file on disk has been modified outside libgit2).
*
* 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. Those options are bundled
* together as `GIT_STATUS_OPT_DEFAULTS` if you want them as a baseline.
