e900d494dc (diff: add an API for deferred freeing, 2021-02-11) added a way to allow reusing diffopts: the no_free bit. 244c27242f (diff.[ch]: have diff_free() call clear_pathspec(opts.pathspec), 2022-02-16) made that mechanism mandatory. git fast-export doesn't set no_free, so path limiting stopped working after the first commit. Set the flag and add a basic test to make sure only changes to the specified files are exported.
