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 tha 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

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.
