ZF-5975: B.4.6.1. If/Else/Elseif: wrong use of spaces in example
The second example in B.4.6.1. uses 3 spaces to indent instead of 4. It violates the coding standard 3 times.
This mistake is in English and German version (didn't check others).
Also there is "elseif" instead of better "else if". See ZF-3723
