 * List pull requests

 * Returns all pull requests on the specified repository.

By default only open pull requests are returned. This can be controlled

using the `state` query parameter. To retrieve pull requests that are

in one of multiple states, repeat the `state` parameter for each

individual state.

This endpoint also supports filtering and sorting of the results. See

filtering and sorting for more details.
