Retain NL to NLCR conversion on the real tty and skip it on the pty

we allocate. That way, if stdout is not a pty there are no extra carriage
returns.

Go back to dropping out of the select() loop when the process dies; Linux
...
ptys apparently don't behave the same as BSD in regards to select().
No need to flush remaining output to the transcript, only to stdout.
Add back code to check the master pty for additional data when we exit
the main select loop.
