That's because the script command opens a new terminal device and records
activity from the "master" end of the psuedo-terminal.

  $ tty
  /dev/pts/0
  $ script
  Script started, file is typescript
  sh-3.2$ tty
  /dev/pts/4

This means that it's already gone through the TTY driver and the "stty"
settings I described earlier have had effect.  In particular the NL->CRNL
translation.  It's the same as if you'd hooked something to a serial
port and recorded all the output from that.

If you use the "tee" command to split the output of a command then
you don't see this.
