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.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.60/etc/DEBUG for instructions.
