+ * 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

+ * whether the file is already in the index or commited to the repository.

+ * One way to think of this is if you were to do "git add ." on the
+ * directory containing the file, would it be added or not?

+ * @param repo a repository object

+ *         of whether it exists or not), or an error < 0 if they could not.
