Emacs ruby mode

This is a fork of ruby-mode.el in elpa with a few changes to the indentation rules. This is the style we use at Nearbuy Systems (http://nearbuysystems.com).

Closing Paren

The first change makes closing parens move up one indent level. Before:

Module.method(
  :arg1 => 1,
  :arg2 => 2
  )

After:

Module.method(
  :arg1 => 1,
  :arg2 => 2
)

Multi-level Nesting

The other change makes multi-level data structures not change the indent level more than once if more than one opening character is on the same line. Before:

array_of_hashes = [{
    :1 => 2
  }, {
    :3 => 4
  }]

After:

array_of_hashes = [{
  :1 => 2
}, {
  :3 => 4
}]

Note that the parser gets confused if you have different opening and closing styles:

array_of_hashes = [{
  :1 => 2
}, {
  :3 => 4
}
]
