struct.c: don't explain implementation details

of keyword_init option. [DOC] [ci skip]

It's implemented to take Hash, but it's just implementation detail and
it's intended to behave in the same way as keyword arguments (for
:keyword_init option too).

Also I unified coding style of r61137 with other places.
