[docs] DOCS - (regex error?)

[EQ mandingo]

https://pypi.python.org/pypi/regex

I believe there is an error in the example expression used in the docs.

*"In the regex (\s+)(?|(?P<foo>[A-Z]+)|(\w+) (?P<foo>[0-9]+) there are 2
groups:"*


The "(?|" has no closing ")" in the expression, I have not tested this but
just seeing this and breaking it down across line breaks makes my brain
immediately go to PCRE mindset and say this expression is broken.  Am I
missing something?

(\s+)
(?|
(?P<foo>[A-Z]+)
|
(\w+)
 (?P<foo>[0-9]+)
