Inital setup:
-------------

The `messages` constant is used to define any messages that we will
need in our component. In our case, these are the various confirmation
messages used with statuses.

*/

const messages = defineMessages({
  deleteConfirm : {
    id             : 'confirmations.delete.confirm',

    defaultMessage : 'Block',
  },
});

                            /* * * * */

/*

State mapping:
--------------

The `mapStateToProps()` function maps various state properties to the
props of our component. We wrap this in a `makeMapStateToProps()`
function to give us closure and preserve `getStatus()` across function
calls.

*/

  const getStatus = makeGetStatus();

    let status = getStatus(state, ownProps.id);

      // work-around: find first good status
      for (let k of state.get('statuses').keys()) {
        status = getStatus(state, k);
        if (status !== null) break;
      }

    let account = undefined;
    let prepend = undefined;

/*

Here we process reblogs. If our status is a reblog, then we create a
`prependMessage` to pass along to our `<Status>` along with the
reblogger's `account`, and set `coreStatus` (the one we will actually
render) to the status which has been reblogged.

*/

    if (reblogStatus !== null && typeof reblogStatus === 'object') {
      account = status.get('account');
      status = reblogStatus;

Here are the props we pass to `<Status>`.

/*

Dispatch mapping:
-----------------

The `mapDispatchToProps()` function maps dispatches to our store to the
various props of our component. We need to provide dispatches for all
of the things you can do with a status: reply, reblog, favourite, et
cetera.

For a few of these dispatches, we open up confirmation modals; the rest
just immediately execute their corresponding actions.
