Import ruby-electric.el 2.0.1, a bug fix release.

* misc/ruby-electric.el: Import ruby-electric.el 2.0.1 which fixes
  a bug and a flaw with auto-end introduced in the revamp.

  * ruby-forward-sexp is inappropriate here because it moves the
    cursor past the keyword.

  * Fix a reversed looking-back check in
    ruby-electric--block-beg-keyword-at-point-p.

  * Do not add end again if space or return is hit repeatedly
    after a block beginning keyword.
