/**
 * Add ignore rules for a repository.
 *
 * Excludesfile rules (i.e. .gitignore rules) are generally read from
 * .gitignore files in the repository tree or from a shared system file
 * only if a "core.excludesfile" config value is set.  The library also
 * keeps a set of per-repository internal ignores that can be configured
 * in-memory and will not persist.  This function allows you to add to
 * that internal rules list.
 *
 * Example usage:
 *
 *     error = git_ignore_add_rule(myrepo, "*.c\ndir/\nFile with space\n");
 *
 * This would add three rules to the ignores.
 *
 * @param repo The repository to add ignore rules to.
 * @param rules Text of rules, a la the contents of a .gitignore file.
 *              It is okay to have multiple rules in the text; if so,
 *              each rule should be terminated with a newline.
 * @return 0 on success

/**

 * This function checks the ignore rules to see if they would apply to the
 * given file.  This indicates if the file would be ignored regardless of
 * whether the file is already in the index or committed to the repository.
 *
 * One way to think of this is if you were to do "git check-ignore --no-index"
 * on the given file, would it be shown or not?
 *
 * @param ignored boolean returning 0 if the file is not ignored, 1 if it is
 * @param repo a repository object
 * @param path the file to check ignores for, relative to the repo's workdir.
 * @return 0 if ignore rules could be processed for the file (regardless
 *         of whether it exists or not), or an error < 0 if they could not.
