with syntax causes problems with show-paren-mode

[jclosure]

with syntax confuses show-paren-mode. Jarring visual artifact (large highlighted blocks of show-matching-paren face) when point is positioned in column 0, to the left of the with statement.

Config:

(show-paren-mode 1)
(setq show-paren-delay 0)

Elixir Code:

defmodule Example do

  def example do
    with a = 1,
         b = 2,
         c = 3,
         d = 4
    do
      IO.puts("weird")
    end
  end

end

Is this an addressable bug in elixir-mode or show-paren-mode?

[dgutov]

Some of it is a bug, and some of it is unfortunately intended behavior (in SMIE).

I think we'd be best off installing the following workaround:
