23.0.60; rx docstring has duplicate (backref N) lines

[Trent W. Buck]

In the rx function's docstring,

| `(backref N)'
|     matches what was matched previously by submatch N.
|
| `(backref N)'
|      matches what was matched previously by submatch N.
|
| `(backref N)'
|     matches what was matched previously by submatch N.

should simply be

| `(backref N)'
|     matches what was matched previously by submatch N.
