Subsequent prompts after first do not print when specifying optional stdout stream

[limulus]

TL;DR: It’s because of a bug in a dependency: isaacs/read#23, npm/mute-stream#5

When using the stdout option to prompt.start(), the specified WriteStream instance winds up getting closed after the first prompt, and all subsequent prompts do not get printed. The following code reproduces this issue:

var prompt = require("prompt")
var tty = require("tty")
var fs = require("fs")

var ttyFD = fs.openSync("/dev/tty", "r+")
var ttyWS = new tty.WriteStream(ttyFD)

prompt.start({ stdout: ttyWS })
prompt.get(["1st", "2nd"], function (err, result) {
  console.log(result)
})

The fix for this is probably just to wait for it to be fixed in mute-stream and read, but for now hopefully this report saves someone some frustration.

Someone needs to harry @isaacs to accept that PR and republish.
