`ruby2_keywords` is set only to be `0` in parse.y.
However `args->ruby2_keywords` is initialized with `0` by `MEMZERO`

02:23 AM Ruby Revision 560ec9bf (git): Skip null check for `brace_block`

`brace_block` is `'{' brace_body '}'` or `k_do do_body k_end`.
Both of them are not null so no need to check `$5`. yui-knk (Kaneko Yuichiro)
