Redirecting file to stdin results in TypeError

[kevinoid]

[Note: This is the first of several issues. I'm happy to send PRs for some/all of these, but most need some discussion first.]

When running cat with stdin redirected from a file yields the following result:

$ ./bin/cat < ./index.js 
/tmp/posix-cat/bin/cat:9
cat.on('end', process.stdin.end.bind(process.stdin))
                               ^

TypeError: Cannot read property 'bind' of undefined
    at Object.<anonymous> (/media/linuxdata/kevin/tmp/posix-cat/bin/cat:9:32)
    at Module._compile (module.js:409:26)

    at startup (node.js:134:18)

This is because process.stdin is tty.ReadStream when stdin is a TTY and fs.ReadStream when it is a file.

Do you recall the reason for calling .end() here?

Thanks,
Kevin
