[docs] [issue12162] Documentation about re \number

[Seth Troisi]

Seth Troisi <braintwo at gmail.com> added the comment:

Given David Murray's input I think the example would be best done as 

>>> re.search(r'(\w+) \1', "can you do the can can?") # Matches the duplicate can
<_sre.SRE_Match object at ...>


I want to stress that the documentation is not wrong but confusing, especially for someone unfamiliar with regression expressions.
