[docs] possible bug

[Kari Kinnunen]

Hi,

I found a problem in my code.

This line has no problem ...

m = re.search("'(\\w+.\\w+)", str(args.rule[0]))

... until i add next line..

str = ".*("

Traceback (most recent call last):
   File "....py", line 332, in <module>
     main()
   File "....py", line 122, in main
     m = re.search("'(\\w+.\\w+)", str(args.rule[0]))
UnboundLocalError: local variable 'str' referenced before assignment

If I remove 'str = ..' line, then everything is again ok.

Best regards,

Kari Kinnunen
