FYI changing this can have wide and deep effects.  I worry about places that use
this method and pass a filter_fn which assumes it's only called on a newline
where with this change "all of those" methods will be called on carriage return.

"All of those" in quotes because I don't have an accounting of how many places
that is.  Hmm.

         in_byte = kid.stdout.read(1)
       # Flush the rest of buffered output. This is only an issue with
       # stdout/stderr not ending with a \n.
