Format the depencies in mix.exp without the additional square brackets

[pragdave]

The package pages on expm show the mix dependency as

{:amnesia,"0.0.1",[github: "meh/amnesia", tag: "v0.0.1"]}

I've been writing about managing projects in Elixir, and I recommended folks copy and paste these lines into their mix.exs files. When José reviewed it, he suggested that it would be better without the [ and ]

{:amnesia,"0.0.1", github: "meh/amnesia", tag: "v0.0.1"}

I've put together a change for this. It's a little ugly—I suspect there's a smarter way of doing it—but I though you might want to consider it.

Cheers

Dave

Dave,

I somehow managed to miss this pull request. Let me think about it, but it feels to me that I'd rather have elixir's inspect have an option for this kind of cases. @josevalim ?
