Due to some breaking changes in Go's standard library which we need,
e.g., https://code.google.com/p/go/source/diff?spec=svn733fefb1deae5490f2d6fcf498667a9077f92a42&r=733fefb1deae5490f2d6fcf498667a9077f92a42&format=side&path=/src/pkg/net/http/transport.go

Technically, anything in the third argument is passes as a string, so you can look at any file if you know the hash (for instance, `blob/HASH/app/index.js`. However, having the issue number passed seems to me to be something really useful to my workflow, so I was hoping to find something in the documentation about it. 

Another possibility would be to enable a fourth argument for issue number. I'm happy to do a PR for this if something things it might be of more worth than just this edit.

- "git protocol for read and ssh for write" had introduced
  additional expectations of behavior.

- Ruby is not required at runtime anymore
- Most installation instructions are now obsolete. Will need to write
  new instructions when we distribute precompiled binaries.
- Remove tedious parts about slowness. It's not slow anymore!

This feature is likely to get dropped from GitHub API in the near
future. The alternative is to simply create a new pull-request and
reference the original issue in the description.

Don't suggest standalone install via curl anymore because:

- hub may not be a single script in the near future
- `rake install` handles the Windows executable as well

Emulates the interface of `git commit`:

  $ hub pull-request -m "This is my title"
  $ hub pull-request -F /path/to/message.txt
  $ hub pull-request -F -

The old way of passing in just title is deprecated

  $ hub pull-request "Deprecated title"
