  #8620: Cmd no longer truncates last character if stdin ends without newline

  Cmd used to blindly chop off the last character of every input line.  If
  the input reached EOF and there was no final new line, it would truncate
  the last character of the last command.  This fix instead strips trailing
  \r\n from the input lines.  While this is a small behavior change, it
  should not break any working code, since feeding a '\r\n' terminated
  file to Cmd would previously leave the \r's on the lines, resulting
  in failed command execution.

  I wrote the unit test in preparation for a PyOhio TeachMe session
  run by Catherine Devlin, and we can thank Catherine and the PyOhio
  session attendees for the fix.  I've added Catherine to the Acks file
  for organizing and leading the TeachMe session, out of which we will
  hopefully get some new contributors.
