  New Revision: 61182

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=61182

  Log:
    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.

    trunk/struct.c
