nit: Insert space after (size_t)

[Dmitry Polukhin, 2014/01/31 17:04:41]

Please don't use C-style cast. Use static_cast<size_t>(5) or IMHO size_t(5) (not
encouraged in style guide but I would object).

[Alexander Alekseev, 2014/01/31 17:21:00]

Done.

[Alexander Alekseev, 2014/01/31 17:21:00]

I've changed it to suffix-style "5u".
