Fill in missing implementation of pty_sendbuffer.

Browse Source 
Going through all the backends' send() and sendbuffer() routines, I
noticed that the Unix pty backend is the only one where the return
value from send() doesn't match what sendbuffer() would tell you,
apparently because sendbuffer() was a stub implementation that I never
got round to filling in properly.

But pty masters _can_ back up, and if they do, we should return the
appropriate data.
