[ANN] readline_buffer 0.9.0 released

Well, I am not going to post the usual announcement, because this
gem is only intended for building autoindent plugin for rib (or ripl).

gem install readline_buffer

Actually this is my first gem which contains a Ruby C extension,
and which only works for MRI or Rubinius using GNU Readline,
not BSD Editline. I'll try to build JRuby extension later, it shouldn't
be too hard.

The reason why I need this is, I want to the auto indention only
putting spaces for me, but not merely printing spaces. The reason
is that auto indention without a real parser is not going to be accurate,
so unexpected indention errors are expected. So there must have
some way to manually adjust this.

I saw ripl-auto_indent is using tput and print, which is ok, but I don't
want to go that path.

I'll put this autoindent plugin under require 'rib/extra/autoindent'
